Ok so I am really annoyed now. I was playing FNV for a while and it was working fine. Then I go to eat supper and when I come back pistols and detonators, even the dart gun, refuse to fire. I have lots of ammo, perfect condition. Nothing should be going wrong. I also can't complete the quest Volare because I cant fire the detonator:(. Please help
