This has been happening for a while but just posting this in case youre somehow not aware.

Also, why is the 1.18 file "1.8" and the 1.19 file "1.12"

Because that's the mod version not MC version. Exains this issue too..

To clarify, I am playing on 1.18.2 forge, using the 1.8 version of your mod

Odd, it did not crash this time when I went in to test it again. But I'll let you know if it happens again.
