I'm playing the french version of the game (so, i'm sorry for the bad english, i ll try to explain what happens.)
I've met a serious "bone" problem attached to female bodies, i'm taking tequila for an exemple but it happens to all female marines, their shoulders are really "short", when tequila is in a scripted animated sequence when she talks as if it was some kind of cinematic animation her shoulders are "ok" but when she leave the "scripted animation" sequence her shoulders are really bugging and go back into her body a bit, that give her a really ugly shape, as if she had the shoulders of a dwarf, it annoys my eyes a lot on any female marine in the game.
I know i'm not really well explaining it, but look at her shoulders, or at a female marine shoulder it's like they got a "scale" or "position" problem on their animations skulls.
Maybe someone else noticed this problem and will explain it better than me.
