Description of the problem

Console spam on server error not being able to save world

I got this issue as well also that it spams every 5 minutes that there is no minecraft:rutile minecraft:dilithium ...

I had this issue as well. Reverting back to an older version of the mod fixed it for me. I'm not sure if the previous version works since I jumped back to version 10.

Had the same thing. World would partial save it seemed, as I could restart the game and my newly created world would only then show up. Removing AR2 was the solution, very sadly.
