Last Cloudia reroll problems usually come from using the wrong reset operation for the symptom. Clearing the in-game cache makes the client download its files again without deleting game data; Data Link protects or moves an account; Delete Account is a separate, irreversible request. Start with the reversible checks below, then follow the path for your platform and the exact error you see. Do not uninstall the app or delete an account merely to cure a download or freeze.
This guide follows Last Cloudia’s official support instructions for mobile and Steam. A reroll that appears unchanged, a download that repeats, a force-quit, a communication error, and a unit missing from the list can have different causes, so applying an account reset to every problem can make matters worse.

What is the difference between clearing cache, Data Link, and deleting an account?
These three menu actions do different jobs. Choose the least destructive one that matches the problem.
| Operation | What it does | Risk and when to use it |
|---|---|---|
| Clear Cache | Removes cached client data and requests a fresh download. The in-game option is documented as preserving game data. | Use for corrupted or repeatedly downloaded files. Expect a large redownload; Wi-Fi is recommended. |
| Data Link | Recovers or transfers play data with a Link Code and numeric Link Password. | Use before changing devices or taking risky troubleshooting steps. Verify the destination Player ID and Player Name. |
| Delete Account | Sends an account-deletion request from the title screen. | Use only when you intentionally want that account gone. Official support says a deleted account cannot be recovered. |
The distinction matters for rerolling. A cache clear is not a new account, and Data Link is not a reset. The official deletion procedure is the only documented account-deletion route in the supplied support material, and it carries permanent-loss risk.

What should I try first when Last Cloudia freezes, force-quits, or will not download?
Begin with reversible device and connection checks before touching account data. Last Cloudia’s freeze guidance recommends restarting the game and device, closing other apps, freeing storage, disabling energy-saving mode, and switching between Wi-Fi and mobile data.
- Close Last Cloudia completely. Remove it from the recent-apps screen rather than leaving it suspended, then launch it again.
- Restart the phone, tablet, or PC. This clears temporary process and network states without changing your account.
- Close background applications. This is especially important on devices with limited memory or when another app is downloading.
- Check free storage. A cache rebuild needs room for temporary and newly downloaded files. Delete or move unrelated files if the device is nearly full.
- Turn off energy-saving mode temporarily. Power restrictions can interrupt a long download or background connection.
- Change the connection. Try Wi-Fi if mobile data is failing, or mobile data if the Wi-Fi session is unstable. Avoid starting a large redownload on a metered connection unless you understand the data cost.
Do not judge a cache rebuild by how quickly it starts. The support page says the download can be large and that its duration depends on the connection. If the game reaches the title screen but repeats the same download after every launch, continue with the cache-specific steps rather than deleting the account.

How do I use Last Cloudia’s in-game Clear Cache safely?
The title-screen Menu > Clear Cache option is the safest documented cache reset. It asks the client to download its data again and is described by Last Cloudia as not deleting game data.
- Stop at the Last Cloudia title screen.
- Open Menu.
- Select Clear Cache.
- Read the confirmation prompt and accept it only when you can allow another download.
- Reconnect over reliable Wi-Fi and leave the game open while the files are retrieved.
Last Cloudia’s support instructions specifically say, “Because it will be a large amount of data you will need to download, we strongly recommend using a Wi-fi connection.” The in-game operation is different from uninstalling: it is intended to refresh downloaded data while retaining play data. A slow connection can make the process look stuck, so allow for the connection’s actual speed before interrupting it.
Changing the in-game Image/Sound quality to Lite also triggers a data download. If you are diagnosing a loop, avoid changing quality at the same time; otherwise you may not know which action caused the new download. The support guidance says LOW graphics or Lite quality may reduce strain on a device, not that either setting guarantees a freeze fix.

Can I clear Last Cloudia’s Android device cache?
Android’s device-level cache control is a separate operation from the game’s title-screen command. Before using it, set a Link Code and numeric Link Password. Do not uninstall Last Cloudia or use a third-party cache-cleaning app: official support warns that game data may be deleted.
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →On Android, the documented path is:
- Open Settings.
- Choose Apps & notifications (the wording can vary by Android version).
- Select Last Cloudia.
- Open Storage.
- Tap Clear Cache, not a control that removes app data.
Menu names differ among Android manufacturers. If you cannot identify a cache-only control, stop and use the in-game Clear Cache option instead. Last Cloudia’s warning is explicit: “Please make sure that you do not uninstall the app, as game data may be deleted.” A third-party cleaner can expose similarly destructive choices without making the distinction clear.
Why is my reroll or reset not changing the account?
A reset that leaves the same account and summons usually means you cleared cached files, not account data. Cache clearing requests a fresh client download; it does not erase the server-side account. If you intend to abandon an account, the title-screen deletion request is a different and irreversible action.
How to request account deletion
From the title screen, open Menu, choose Delete Account, read the warning, agree to it, and select Request for Account Deletion. Do this only when you accept permanent loss. The official support article states that an account deleted through this process cannot be recovered, so it is not a routine remedy for a failed download, freeze, or communication error.
The supplied support documents do not provide a current, universal reroll procedure or guarantee that account deletion is the correct response to a client fault. If the game is malfunctioning, troubleshoot the client first and preserve your account credentials before considering deletion.

How do I protect my account before troubleshooting or changing devices?
Set a Link Code and keep the numeric Link Password somewhere safe before clearing a device cache, moving installations, or experimenting with a reset. This gives you a documented recovery path if the client stops displaying the account you expect.
- On the home screen, open the upper-right Menu.
- Choose System Menu.
- Open Account.
- Select Check/Set Link Code.
- Record the Link Code and the numeric Link Password. The password uses numbers only.
To recover or transfer the data on another installation, open Menu on the title screen, choose Data Link, and enter the credentials. Before confirming, compare the displayed Player ID and Player Name with the account you meant to load. Last Cloudia’s support guidance says linked play data can be used on a maximum of three devices, so treat the link as a controlled recovery or transfer method rather than an unlimited backup system.
Never publish your Link Code and Password in a public support post. If the credentials are written down, distinguish letters in the code clearly and preserve the password exactly as shown.
What fixes repeated downloads, a stuck loading screen, or a force-quit?
Use the cache path first, then remove environmental causes. A repeated download can be normal after a cache clear or a Lite-quality change; it becomes a fault when the same cycle returns after a successful completion and relaunch.
- Confirm storage again after starting the download. A device can have enough room for the initial launch but not for a complete replacement data set.
- Keep the connection stable. Switch networks if the progress repeatedly stops. Wi-Fi is the support-recommended choice for the large cache download.
- Keep the device awake when appropriate. Aggressive battery controls can suspend a long transfer; disable energy-saving mode while diagnosing.
- Do not stack changes. Run one cache operation, let it finish, then test. Changing graphics, clearing cache, and reinstalling simultaneously removes useful clues and increases data loss risk.
- Restart after a failed attempt. A clean launch can distinguish a one-time process failure from a repeatable download loop.
If the game freezes before the title screen, the in-game Clear Cache control may not be reachable. In that case, perform the reversible restart, storage, power, and network checks first. On Android, use the device cache path only after setting a Link Code and Password, and never substitute uninstalling for clearing cache.

What should I do about a Steam freeze or communication error?
Steam troubleshooting is platform-specific. Last Cloudia Support’s Steam article, updated July 16, 2026, says to confirm the operating environment, restart Last Cloudia, sign out of Steam and back in, close other applications, and restart the PC. The support page lists these minimum published requirements:
| Requirement | Published Steam specification |
|---|---|
| Operating system | Windows 10, 64-bit |
| Processor | Intel Core i3-3225, AMD A8-7650K, or similar and higher |
| Memory | 4 GB RAM or more |
| Free installation space | 2 GB or more |
| Graphics | Intel HD Graphics or higher |
These are the publisher’s operating-environment requirements, not an independent performance benchmark or a guarantee that every qualifying PC will run without freezes.
For the specific [Communication Error Occurred] message, the separate official guidance recommends restarting Steam or the PC, signing out and back in, and checking the network environment. Smartphone users are directed to a separate mobile troubleshooting page, so do not apply Steam-only instructions as though they were a universal mobile fix.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Exit Last Cloudia and Steam completely.
- Restart Steam and sign in again.
- Restart the PC if the message returns.
- Check whether another application or network session is consuming the connection.
- Use the mobile-specific support route if the error is occurring on a phone or tablet instead of Steam.
Why is a new gacha unit missing from my Units list?
Before treating a summon as failed, inspect the Unit List for an existing unit marked with a ! icon. Last Cloudia explains that some units share a name but have different appearances called Shifts; a new appearance can therefore be associated with an owned unit rather than displayed as an entirely separate base-name entry.
- Open the Unit List.
- Look for a unit carrying the ! marker.
- Open that unit’s details.
- Use the icon in the upper-left to view or change the available Shift.
The official example is Thunderbolt Sevia appearing as Killer Ice Princess Sevia. This explains one common listing and appearance confusion; it does not prove that every missing summon is a Shift. If no marked unit or matching Shift appears, record the summon details and contact support rather than repeatedly deleting accounts or clearing data.

Could a known issue be causing the freeze?
Check the game’s own notices before assuming your device or account is at fault. From the game, open News > Important > Update Regarding Known Issues. The management team’s July 2025 notice discussed a specific World Raid loading freeze and historical retry guidance; it does not establish a current, general reroll, download, or summon outage.
Known-issue notices can change, and a historical event notice should not be treated as proof that the same problem is active now. Match the notice’s platform, mode, and dates to what you are seeing. If there is no matching notice, continue with the platform-specific support path.

Contact support when the reversible steps fail, the same error returns after a clean restart and cache procedure, or a summon still cannot be located after checking Shifts. Use the official Submit a request form; it accepts email inquiries around the clock, although response time can vary.
Describe the symptom precisely instead of saying only “reroll broken.” Include whether you are on Android, iOS, or Steam; whether the failure occurs before or after the title screen; whether the download completes and repeats; and the exact wording of any communication error. For a missing unit, state which Unit List entries you checked and whether a ! marker or Shift was present. Do not send your Link Password in an open post or an unnecessary message.
A quick decision path for “reroll not working”
- Is the game freezing, force-quitting, or downloading? Restart the game and device, close other apps, free storage, disable energy-saving mode, and switch networks.
- Can you reach the title screen? Use Menu > Clear Cache, then allow the large redownload over Wi-Fi.
- Are you on Android and considering device cache clearing? Set a Link Code and numeric Password first; clear cache only through the system’s cache control. Do not uninstall.
- Is the goal a genuinely new account? Read the deletion warning and use Delete Account only if permanent loss is acceptable. Cache clearing will not create a new account.
- Are you transferring or recovering progress? Use Data Link, then verify Player ID and Player Name before confirming.
- Is the problem on Steam? Follow the Steam restart, sign-out, network, and PC requirement guidance rather than mobile-only steps.
- Is a summoned unit absent? Check the Unit List’s ! marker and Shift selector before concluding the pull failed.
- Still stuck? Read News > Important > Update Regarding Known Issues and submit a support request with the exact symptom and platform.
Frequently Asked Questions
Does clearing the cache reset my reroll account?
No. The in-game Clear Cache command requests a new download of client data; it is not an account-deletion or account-creation action. If you are trying to preserve progress, link the account before using device-level troubleshooting.
Is reinstalling Last Cloudia a safe way to fix a download loop?
Official support specifically warns against uninstalling because game data may be deleted. Use the title-screen Clear Cache option and the reversible restart, storage, power, and network checks first.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsWhy should I verify the Player ID during Data Link?
The confirmation screen is your chance to catch a wrong Link Code or password before loading the wrong play data. Compare both the Player ID and Player Name with the account you intended to recover.
What does the “!” icon mean when a gacha unit is missing?
It can identify an existing unit that has a newly available Shift or appearance. Open that unit’s details and use the upper-left icon to inspect the Shift before reporting the summon as absent.
