Why do my buildings disappear in Valheim multiplayer?

Buildings disappearing in Valheim multiplayer can be a frustrating issue, but it often stems from specific game mechanics or technical problems. Valheim uses a shared world system where the host player''s world is the primary instance. If the host leaves the game or the server shuts down, any changes made by other players, including building structures, may not save properly. This is because the game relies on the host''s world file to store all progress, and if the host disconnects unexpectedly, unsaved changes can be lost.\n\nAnother common cause is the game''s stability in multiplayer mode. Valheim is still in early access, and multiplayer sessions can sometimes experience bugs or crashes. If the game crashes while players are building, the structures may not save correctly. Additionally, if players are building in areas far from the host''s spawn point, the game may struggle to load and save those areas properly, leading to disappearing buildings.\n\nTo prevent buildings from disappearing, ensure that the host player remains in the game until all players have logged out safely. This allows the game to save all changes properly. If you''re hosting a dedicated server, make sure the server is configured to save progress regularly. You can also manually save the game by typing /save in the console if you''re hosting a local game. This forces the game to save all current progress, reducing the risk of losing buildings.\n\nAnother practical solution is to avoid building in areas far from the host''s spawn point until you''ve established a stable connection. Building near the starting area or in biomes like the Meadows or Black Forest can help ensure that the game saves your structures properly. If you''re venturing into more dangerous biomes like the Swamp or Mountains, consider setting up a small base near the host''s spawn point first to test the stability of your multiplayer session.\n\nIf buildings still disappear despite these precautions, it may be due to corrupted world files. In this case, you can try restoring a backup of the world file. Valheim automatically creates backups of your world files, which can be found in the game''s save folder. To restore a backup, navigate to the save folder, locate the backup file, and rename it to replace the corrupted world file. This can often recover lost structures.\n\nFinally, ensure that all players are using the same game version and mods, if any. Incompatible mods or outdated game versions can cause instability in multiplayer sessions, leading to disappearing buildings. If you''re using mods, make sure they are compatible with the current version of Valheim and that all players have the same mods installed.\n\nBy following these steps, you can minimize the risk of losing buildings in Valheim multiplayer. Always prioritize stable connections, regular saves, and cautious building practices to ensure your Viking settlements remain intact.
