Crashes with C2ME (no config changes) enabled upon world generation.

Looking through issues and whatnot I realize this issue is related to #51
Unfortunately we do not support 1.18 anymore, and as such its extremely unlikely an official release will be made. Luckily the related PR did get a release on GitHub, and can be downloaded here:

Looking at it you probably need their updated version of owo-lib as well, due to some issues related to sentinel:

I have tested these fixes and they do seem to work with C2ME

Works! Thank you

But due to how many mods I'm using, I will try it without things. I know at least ONE of the issues were things. but let me verify if its only things. could have been fixed with this build but it could be something else.

Edit:
Yeah, no. I removed things and it was completely fine. It's just things causing it. This build didn't solve the issue, I'm afraid.

Could you try this with the no-cme build of owo-lib? It is available here: https://www.curseforge.com/minecraft/mc-mods/owo-lib/files/3824297
