After looking at other issues it seems this may be related to #2964

[JBYoshi]

Seems like this is really about SGCraft. It has the extra villager registration, and owns one of the mixins in the stack trace which replaces the profession.

[MetaverseRPN]

I can see why that would be the case but why is none of the log mentioning sgcraft at all in the tracelog then?

[JBYoshi]

The reason SGCraft doesn't appear in the crash is because its code is part of a mixin. It's part of the following line:

        at net.minecraft.world.gen.structure.StructureVillagePieces$Village.redirect$onSetProfessionViaStructureSpawn$bbi000(StructureVillagePieces.java:2015)

Most of the mixins in a Sponge server belong to Sponge, so I tried looking it up in Sponge first. However, onSetProfessionViaStructureSpawn never appears in the Sponge codebase. A full search on GitHub showed the only result for that as part of SGCraft.

[MetaverseRPN]

I guess that makes sense. So should I post this bug there also?

[JBYoshi]

Not at this point. I think it's probably a Sponge bug which shows up when used with SGCraft. (The majority of bugs that involve Sponge and don't appear without it are caused by it.)
