I have an M4 CCO SD rifle and have picked up a bunch of regular m4 ammo but the game will not allow me to load it into my silenced rifle. Is this game mechanics or am I doing something wrong?

Just minding my own business approaching Novy Sabor when all of a sudden I lost control of my character. This occurred for several seconds. I couldn't move or do anything. When I got control back my inventory was loaded with all sorts of gear, night vision, range finder, gps, an AS50 with a full compliment of ammo, a silenced m4 in my backpack with ammo... I suspect this was a hack... has this happened to anyone? I am not sure what to do because I do not want to get banned for having something I shouldn't... I have a good mind to dump it all but my original enfielf and pistol are gone and I don't want to be left defending myself with nothing.

Love how folks split hairs over little things.
