How do I resolve the "World Save Corrupted" error in multiplayer?

The ''World Save Corrupted'' error in Valheim multiplayer can be a frustrating issue, but it is often fixable with the right steps. This error typically occurs when the game fails to save or load your world data correctly, which can happen due to crashes, improper shutdowns, or file corruption. Understanding the game''s save mechanics is crucial to resolving this issue. Valheim saves world data in two files: a .fwl file (world metadata) and a .db file (world content). If either of these files becomes corrupted, the game may fail to load the world.\n\nTo begin troubleshooting, first locate your Valheim save files. On Windows, these are usually found in the AppData\LocalLow\IronGate\Valheim\worlds folder. You can access this by typing %appdata% in the Run dialog (Windows key + R) and navigating to the LocalLow folder. For Linux and Mac users, the save files are typically located in the ~/.config/unity3d/IronGate/Valheim/worlds directory. Once you locate the files, make a backup of your entire Valheim folder to prevent further data loss.\n\nIf the world save is corrupted, you can attempt to restore it using a backup. Valheim automatically creates backup files with the extensions .fwl.old and .db.old. To use these backups, rename the corrupted files by adding a .corrupted extension (e.g., MyWorld.fwl.corrupted) and then remove the .old extension from the backup files. This will restore the most recent backup of your world. If this doesn''t work, you may need to manually restore an older backup or use a third-party tool like Valheim Save Shard Repair to fix the corrupted files.\n\nAnother common cause of the ''World Save Corrupted'' error is mismatched mods or outdated game versions. If you or your friends are using mods, ensure that all players have the same mods installed and that they are compatible with the current version of Valheim. Mod conflicts can cause save file corruption, especially if the mods alter world data. Additionally, make sure everyone in the multiplayer session is running the same game version. You can check for updates on Steam by right-clicking Valheim in your library, selecting Properties, and navigating to the Updates tab.\n\nIf the issue persists, consider creating a new world and transferring your character and items. While this is not ideal, it can be a last resort if the corrupted world cannot be recovered. To do this, log into the corrupted world with your character, gather all your items, and store them in your inventory. Then, log out and join a new world. You can use console commands (if enabled) to spawn items if necessary, but this should be done sparingly to maintain the game''s balance.\n\nTo prevent future corruption, always exit the game properly by logging out of your character and quitting to the main menu before closing the game. Avoid shutting down your computer or disconnecting from the server abruptly, as this can interrupt the save process. Regularly back up your world files manually by copying them to a separate folder or cloud storage. This ensures you have a recent save to fall back on if corruption occurs.\n\nIn summary, the ''World Save Corrupted'' error can often be resolved by restoring backups, ensuring mod compatibility, and maintaining consistent game versions across multiplayer sessions. Regular backups and proper shutdown procedures are key to preventing this issue. If all else fails, transferring your character and items to a new world can save your progress. By following these steps, you can minimize downtime and continue your Viking adventures in Valheim.
