Hello,
I was wondering if moving to Valheim+ and playing in a world for a while with different configs, saving the world, then switching back to stock Valheim causes any integrity or other issues for the Valheim world file or Valheim world in general?
Thank you,

I was having the same problem. Try this... worked for me.
Ensure you have a world backup before continuing!
First, check the box to "Delete World Save", and click "Save Settings and Restart Server".
Now ensure the zip file has the two files in it - the .db and .fwl world file(s).
Once the server is completely up and running again, then browse and select the .zip file in the local save area.
Once again, click "Save Settings and Restart Server".
Wait a few min and connect. It worked for me. I transfered my world from another home-built server and it worked fine.
