I am running an exaroton server (1.19.2 Forge 43.2.23) with some friends with a lot of mods installed, after a while we got bored of the mods we had and installed a set of new ones, then we selected some chunks with mca selector in our world to delete so new things would spawn. The problem is that after that the server instantly crashes if someone enters it.
Here's the crash report: https://hastebin.com/share/ocujopudes.perl
