This bug has been fixed in the latest version, please close this.

This bug might be fixed in the new 1.19.3 and 1.18.2 versions, but I've been having the same problem in my 1.19.2 world, as the most recent patch to the mod has not been released to that version.

1.19.2 has been updated to fix this crash issue

yo can we do 3.1.1.1.1

I'm getting this error in a 1.16.5 version as well

You should not be getting this same error. I recommend opening a new issue and attaching your crash report/log
