How to fix Valheim server saying "missing world"
You may encounter issues where you deleted a world by accident or want to use a new world and you're trying to upload/reupload the files from an archive, this is where file permissions are important.
For e.g your console will say "missing /home/container/.config/unity3d/IronGate/Valheim/worlds_local/Dedicated.db"
Locate your world files in the file manager.

In the screenshot above, this will be the Dedicated.db and Dedicated.fwl files.
Right click both of these files individually and set the permissions to 755

Restart your server and your world will now be loaded.
If you require any further assistance, please create a ticket here.
