May be one of your tc3d model read problems, I have checked your textures and data, they do not have any problems, because tc3d can not be decompiled, so only you to troubleshoot your mod read problems.

I'm not sure why it's causing issues with the Sheephead, I never touched those files, but I'll look into it. As for the unused models, this was originally supposed to be a larger pack but I scrapped the rest, although they should've been fully removed.

This mod has a number of unused models that currently cause texture loss in the California Sheephead in BLUE-Strange Creatures Strange Names.
