I just got back to playing this game, and when i finally finished installing my mods, i discovered a wierd bug, whenever i fire a non-energy weapon, a red ! pops up, any ideas to what might have caused this?

a red ! is telling you, your missing a texture or mesh, if firing a fook weapon causes this you probably should reinstall fook your missing a projectile mesh or texture i would think
