How do I troubleshoot the "World Save Not Found" error in multiplayer?

The ''World Save Not Found'' error in Valheim multiplayer can be frustrating, but it often stems from issues with world file synchronization or server settings. This error typically occurs when the game cannot locate the world file that the host or server is trying to load. Understanding the game mechanics behind world saves and multiplayer hosting is key to resolving this issue.\n\nFirst, ensure that the world file exists on the host''s system. In Valheim, world saves are stored locally on the host''s computer. For Windows users, these files are usually located in the ''C:\Users\[YourUsername]\AppData\LocalLow\IronGate\Valheim\worlds'' directory. If the world file is missing, the game will display the ''World Save Not Found'' error. To fix this, the host should verify that the world file is present and properly named. For example, if the world is named ''MyVikingAdventure'', there should be two files: ''MyVikingAdventure.db'' and ''MyVikingAdventure.fwl''.\n\nIf the world file is present but the error persists, the issue may lie with the server settings. When hosting a dedicated server, the server configuration file (usually named ''start_headless_server.bat'') must specify the correct world name. Open this file with a text editor and ensure the ''-world'' parameter matches the exact name of the world file. For example, if the world file is named ''MyVikingAdventure'', the line should read ''-world MyVikingAdventure''. Any mismatch will cause the ''World Save Not Found'' error.\n\nAnother common cause is file corruption or incomplete synchronization. If the host recently migrated their world file to a new system or cloud storage, the file may not have transferred correctly. To resolve this, the host should re-upload or copy the world file to the correct directory. Additionally, ensure that both the ''.db'' and ''.fwl'' files are present, as both are required for the world to load properly.\n\nFor players using third-party hosting services, the issue may stem from incorrect file paths or permissions. Many hosting platforms require users to manually upload world files via an FTP client or web interface. Double-check that the files are uploaded to the correct directory and that the server has read/write permissions for the world files. If the hosting service provides a control panel, verify that the world name is correctly specified in the server settings.\n\nIf the error occurs after a game update, it may be due to compatibility issues. Valheim updates occasionally introduce changes to world file formats or server configurations. In such cases, the host should check the official Valheim patch notes or community forums for guidance. Sometimes, updating the server software or reinstalling the game can resolve compatibility issues.\n\nFinally, ensure that all players are using the same game version. Mismatched versions between the host and clients can cause the ''World Save Not Found'' error. To check the game version, open Valheim and look at the bottom-right corner of the main menu. If versions differ, update the game through Steam or your preferred platform.\n\nPractical tips for avoiding this error include regularly backing up world files, using descriptive and unique world names, and verifying server settings before starting a session. For new players, it''s also helpful to test the world in single-player mode before hosting it in multiplayer. Experienced Vikings should consider using mods or tools like Valheim Plus to streamline server management and reduce the likelihood of errors.\n\nBy following these steps, you can troubleshoot and resolve the ''World Save Not Found'' error, ensuring a smooth multiplayer experience in Valheim.
