Minecraft v1.18.1
Forge v36.1.2
Malum v1.3.2
Ceiling Torch v1.15

Malum had an update, which now causes a crash with Ceiling Torch.
I also just saw that this was fixed for 1.18.2, but not for 1.18.1 if it's still being supported.
Crash Report

Already fixed in v1.16 (no issue present) and again in v1.16.1 (#56). I no longer support 1.18.1 in favor of 1.18.2.

Alright, good to know, thanks.
