Anything else

Note that I was experiencing this issue on my modpack called 'Insomnia: Hardcore'. I don't know if this is caused by an incompatibility or not, since I have not tested it on its own.

Same on 1.19.2. Doesn't appear to be an incompatibility, since it's referencing a missing class.

Uhh, frick. That's the hanging sign. Yeah I forgot to check Minecraft version again 💀

I moved hanging signs to OptiGlue 1.19.3 (where other 1.20 features are).
I'll release a quick hotfix update after having some sleep

I'll look into testing for this type of crash in the future. A hotfix should be available soon.
