Let me explain. In Coop when someone steals and item and does not drop it into it's own inventory but directly sends it to the other players inventory, the second player get caught. Not the stealer.
Not a main issue, just that it feels totally wierd ...
I usually go cooking in the guard camp on Act 1 and my pal empties all the crap around. When he gets caught red-handed ... i'm the one getting swarmed by guards T_T
