How do I fix the "World Save Failed" error in multiplayer?

The ''World Save Failed'' error in Valheim multiplayer can be frustrating, but it is often caused by issues with file permissions, corrupted save files, or server-client synchronization problems. This error typically occurs when the game is unable to save your progress, which can lead to lost data or an inability to load your world. Understanding the game mechanics and taking proactive steps can help you resolve this issue and prevent it from recurring.\n\nFirst, check your file permissions. Valheim requires proper read and write access to its save files, which are stored in your local AppData folder. On Windows, navigate to ''C:\Users\[YourUsername]\AppData\LocalLow\IronGate\Valheim\worlds''. Ensure that your user account has full control over this folder. Right-click the folder, select ''Properties,'' go to the ''Security'' tab, and verify that your account has ''Modify'' and ''Write'' permissions. If not, adjust the permissions accordingly.\n\nNext, verify the integrity of your save files. Corrupted save files can trigger the ''World Save Failed'' error. To check for corruption, locate your world files in the same folder mentioned above. Look for files with the extensions ''.fwl'' (world metadata) and ''.db'' (world data). If these files are unusually small (less than 1 KB) or missing, they may be corrupted. In such cases, restore a backup if you have one. Valheim automatically creates backups in the same folder, labeled with a ''.old'' extension. Rename the backup files by removing ''.old'' to restore them.\n\nIf the issue persists, consider restarting your server or game client. Sometimes, the error is caused by temporary synchronization issues between the server and clients. Close the game completely, restart your computer, and relaunch Valheim. For dedicated servers, restart the server software and ensure all players are using the same game version. Mismatched versions can cause save errors and other multiplayer issues.\n\nAnother common cause is insufficient disk space. Valheim requires adequate storage to save world data. Check your hard drive''s available space and free up storage if necessary. If you''re hosting a dedicated server, ensure the server machine has enough disk space as well. Running out of space can prevent the game from saving properly.\n\nFor players experiencing this error on a dedicated server, ensure the server has proper write permissions for the save folder. On Linux servers, use the ''chmod'' command to grant the necessary permissions. For example, run ''chmod -R 777 /path/to/valheim/save/folder'' to allow full access. Additionally, check the server logs for any error messages related to file access or saving.\n\nIf none of these steps resolve the issue, consider reinstalling Valheim. A fresh installation can fix corrupted game files or missing dependencies. Before reinstalling, back up your save files to avoid losing progress. After reinstalling, restore your save files to the appropriate folder.\n\nFinally, to prevent future issues, regularly back up your world files manually. Copy the ''.fwl'' and ''.db'' files to a separate location, such as an external drive or cloud storage. This ensures you have a recent backup in case of corruption or other errors. Additionally, keep your game and server software up to date to avoid compatibility issues.\n\nBy following these steps, you can resolve the ''World Save Failed'' error and ensure a smoother multiplayer experience in Valheim. Whether you''re a new player or an experienced Viking, these troubleshooting tips will help you maintain your progress and enjoy the game without interruptions.
