Hello everyone my nickname in game is -*NymeK*- , about two days ago i am entering crossfire, in my storage I noticed that I had the Thompson, but I never won this weapon, they look better than I have seen this weapon was a TIME . At the beginning I thought it was a graphic bug and I decided to get into game to see what's going on, to my surprise the Tompson function, namely: firing, killing and did not make me quit the game. Can you explain what happened? If I also want the screen to show you.

Sorry if my English is not good, but I'm Italian
