Hey,
Like the title tells you, the game plays the wrong animation for NPCs and players alike when wearing the core-tech suit.
If i shoot to the east, the animation for shooting into the north fires.
So to oversimplify it.
If i shoot to the west, i look to the north while i'm firering.
I think you messed up the animation allocation. (I think. It's just a guess.)
