As I wrote in subject. In single player and multiplayer mode I have the same problem. My guns are magic and don't need any mouse button click to fire. It's annoying. I'm in "cloack engaged" mode, going invisible and suddenly gun fires without any action from my side. Nonosuit energy is gone, I'm visible and everybody is shooting. I can handle this on single player thanks to stupid enemies but couple minutes ago I've started multi and it was tragedy.

Does anybody know how to fix this?
