For some reason, whenever I check one of the boxes on the armor GUI to hide a body part, the box unchecks once I exit and does not hide my body. How can I fix this? My EBM is updated to the latest along with chisel and bits, and they are the only two mods I have right now, so they aren't conflicting with anything else.

I also had them in a modpack earlier and got this crash report when I tried to toggle the body parts,
