crashlog

FastWorkbench (1.6.0) also seems to cause problems. The crash log gives little information (to me at least), but the game worked fine after I removed these too, so I'm fairly certain it's for one of these.

EDIT: Running Forge 1.12.2 14.23.5.2776

This isn't being caused by either of my mods. I think something is probably reacting badly to registry replacements, but I don't know what.
