This bug have to do with guns, its a bug on all type of guns. If u have a gun in your hand and then aim if you then press Y (to relod) then u shoot. You will not see or hear but other players will, but if you take out your mag then u will se that you are missing a bullet. And that not the only bug with guns. I pickt up M4 with a mag in it. The problem was that I could not take out the mag or shot with the gun -_-
