Picking up ammo packs with e is a cool idea, I'll look into why it's not giving opfor grenades
The reason it messes with painting is so that you can bipod your weapon even in minigames with painting enabled, which was a requirement for the gamemode I want to make for this pack, but I haven't worked out all the kinks in that system yet. It's supposed to account for different minigame settings, I'm guessing it's breaking?
