How do I fix 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 properly, which can happen due to crashes, improper shutdowns, or file corruption. Understanding the game''s save mechanics is crucial: Valheim saves world data in the ''worlds'' folder and character data separately. If the world file becomes corrupted, you may lose progress unless you have a backup.\n\nTo fix this issue, the first step is to locate your save files. On Windows, these are usually found in the ''AppData\LocalLow\IronGate\Valheim\worlds'' directory. You can access this folder by typing ''%appdata%'' in the Run dialog (Windows key + R) and navigating to the correct path. Look for files with the same name as your world, which will have extensions like ''.fwl'' (world data) and ''.db'' (world database). If these files are corrupted, you may need to restore from a backup.\n\nIf you have a backup, replace the corrupted files with the backup versions. Valheim automatically creates backups named ''worldname.fwl.old'' and ''worldname.db.old''. Rename these files by removing the ''.old'' extension to restore them. For example, if your world is named ''Midgard'', rename ''Midgard.fwl.old'' to ''Midgard.fwl'' and ''Midgard.db.old'' to ''Midgard.db''. This should restore your world to its previous state.\n\nIf you don’t have a backup, you can try using third-party tools like Valheim Save Shard Repair Tool, which can sometimes recover corrupted save files. However, this is not guaranteed to work, so prevention is key. To avoid future corruption, always exit the game properly by using the ''Quit'' button in the menu. Avoid force-closing the game or shutting down your computer while the game is running, as this can interrupt the save process.\n\nFor multiplayer hosts, ensure your server software is up to date and compatible with the latest Valheim version. If you’re using a dedicated server, regularly back up your world files manually by copying them to a separate location. This is especially important if you’ve spent significant time building structures or exploring biomes like the Plains or Mistlands, where progress can be hard to replicate.\n\nFinally, if all else fails, you may need to start a new world. While this can be disappointing, it’s an opportunity to apply what you’ve learned and optimize your gameplay. For example, you can focus on building a more efficient base or exploring biomes in a different order. To minimize the impact of losing progress, consider using console commands to restore items or structures, though this is optional and depends on your playstyle.\n\nIn summary, the ''World Save Corrupted'' error can often be resolved by restoring from backups, using third-party tools, or taking preventive measures. Always back up your world files regularly, exit the game properly, and keep your server software updated. By following these steps, you can minimize the risk of losing progress and enjoy a smoother multiplayer experience in Valheim.
