I was testing my pack, making single player worlds while waiting for the curse approval, and I had just placed down a prefab, opened the chest with items provided, and went to shift click the leather armor into their slots and the client crashed.

Pack - https://minecraft.curseforge.com/projects/towncraft/ - A town building modpack for 1.12.2
Version .29

It happened again -

Pack version 1.23

What version of LibLib are you using? ParticleRenderManager.kt only has 299 lines, so I don't see how an error could occur on line 303.

librarianlib-1.12.2-4.7

Assuming fixed in recent version
