Minecraft v1.16.5
Forge v36.1.32
Ceiling Torch v1.13
Infernal Expansion v2.0.0-beta.5

I got this crash during load with Infernal Expansion when using their beta version obtained from Modrinth, since it is not yet available on Curseforge. Though it's understandable if you'd rather wait till it is released on curseforge.
Crash Report

I'll wait until the full release which will be available on CurseForge according to their Twitter account. If they change more during the beta, I'll have to update Ceiling Torch yet again.

The latest update has been released on curseforge: https://www.curseforge.com/minecraft/mc-mods/infernal-expansion/files/3389285

It's still marked as a beta, but I'll just hope I don't have to update Ceiling Torch again due to changes in the same code area.

Thanks! Hopefully not.
