If you're playing Valheim, you need to back up your data right now "The evil world-destroyer bug is still roaming free =(." News by Vikki Blake Contributor Updated on 14 Feb 2021 10 comments Valheim developer Iron Gate is advising all players backup their characters and worlds after discovering a "world-destroyer" bug is resetting progress. In a tweet, CEO Richard Svensson explained how players can make backups and avoid losing their data to the bug, confirming that despite trying to reproduce it and address the glitch, the team hasn't yet been able to do so. However, Iron Gate suspects it may be connected to exiting the gaming by ALT+F4 and not via the menu. Watch on YouTube "If you are playing Valheim this weekend, please backup your world and characters," Svensson said. "The evil world-destroyer bug is still roaming free =(. "It's an evil bug, that we have yet to be able to reproduce even once :(. It seems to occur more often if you exit the game by ALT+F4, so try to use menu->exit instead."
