Bug Description

Immediate CTD when loading a certain chunk with MCTL enabled.

From what I can see this is what happened:
The crash happens inside

com.unlikepaladin.pfm.blocks.models.forge.PFMForgeBakedModel.getQuadsWithTexture(PFMForgeBakedModel.java:109)

That method is building a HashMap/LinkedHashMap of quads while at the same time, Embeddium is trying to render the same block model on another thread and since Minecraft’s model baking/rendering isn’t thread-safe by default, the two mods end up at a ConcurrentModificationException.

Reproduction Steps

Place a stripped oak chair in a chunk, using a mod enable multithreaded chunk rendering, rapidly load the chunk. (In my case I was using the latest version of 1.18.5 embeddium.
