They're using mixins so I can't quickly put out a fix for this. I'm going to remove/replace this feature. I should have it fixed within a day or two. Sorry about that.

I rewrote the way rendering the player works so there shouldn't be any mods that ever break it again. I checked and it fixes compatibility with SkinLayers3D!

Fantastic! Keep up the great work, I really appreciate your quick response and continued dedication to this project.
