if your having mega trouble right click on Valhiem on steam list , properties , local files , browse and then delete every file in there that may have not been deleted only the game files after Common in top search bar . This fixes those cr?ppy mods that make you constantly reset and have mega problems ever running the game again .
Hope this helps
