My bullets don't do damage even without nitePR on. I've tried single player and ad-hoc too, but they also don't work. I don't use any codes besides No Fog, Knife (when I have to), Anti-12 (lobby boot) and custom weapons (putting a Variable Scope on an STG)

I'll try disabling nitePR before I play. CW Cheat caused some weird problem in a game when it was activated, but I wasn't using it. All the enemies flew around buggily.
