Crash on new world (When a treasure2 chest is loaded in?)

I was getting the same error/crash, and after some testing it seems to be Jade causing it.
Also, in my own modpack it seems Supplementaries causing the same error as well

Should be fixed in v3.1.2. This fixes the Jade issue, but Supplementaries has a issue in 1.19.2 - it might be the same thing for 1.18.2
