Talking with the cheeks

It isn’t life without having fuck ups one after the other. So what I have seen from this avatar, its that whenever I speak in game, the left cheek morphs and moves as if its the jaw. Again, this is the first of my avatars that had this problem, I used the same method to upload it. Also, it seems that there are bits of skin missing. The avatar blinks normally, but only the eyelashes move. It seems that this avatar does not have eyelids
