The face flexes are preserved from SFM. Gmod can't handle large face flexes like the jaw opening. I would recommend just moving the jaw bone, but the model lacks one. Nothing I can really do since the model has no face bones (meaning I can't make my own).

I noticed Cynder's mouth glitching out too when I open her mouth.

Cynder's mouth goes weird when I try to open her jaw. This should probably be fixed as soon as possible. Image [imgur.com]

Gaul and Skabb should be coming soon, me and Rofutureman have the models for them, we just need them bone rigged and they will be commissioned

I agree, I can't wait whatever you will think of next. Original model Ignitus, Gaul the Ape King, Captain Skabb, the list is endless on who's going to be commissioned. But can't commissioned any of them though, trust issues and all that sort of thing you know. But still excellent work, Akuago, as usual, carry on and keep up the good work.

keep it going this is what the workshop needs!
