Would you happen to be using eye/face tracking? Other than that, is the blinking still working, and do the eyes still move around and look at things when they're out of the head?

Yeah I sent the files to my friend and they weren't having any issues with the eyes either. All I can suguest is remaking the project from scratch and trying again with a new upload. That, or manually repositioning the eyes so that the rotation states look good. But other than that I honeslty have no idea, sorry I wish I could offer more help.
