Mass Effect 3 Bug?

[odya]

I got a problem, something I don't think I've seen before, although it's been a while since I've had this game installed so I might remember wrong. In any case here's my problem: almost all assault rifles in my game are clipping trough my characters face, and the animations look all screwed up, this might just be a fun little ''feature'' our beloved bioware left in the game but I swear I can't remember ever seeing this issue before. Now I am running a few mods, namely some texture replacers, Brooks Armour for femshep, EGM, Liara Ajax Armour and Alliance Armour pack, but I've never seen anyone have this problem, tried googling and found absolutely nothing. So, here I am, asking you guys if anyone knows whether this is just the game being dumb or if it's a bug or something. It seems to only affect assault rifles, some more than others, namely the M99 saber's stock is literally going trough my characters cheekbone every time I equip it, which is a bit annoying, it's not so bad with some others such as the avenger and vindicator, others like the saber, mattock and valkyrie are literally all over the place.
