HaloMods "Classic" Read-only Archive

I used the tutorial for getting snow into bloodgulch and it worked but now when I try to shoot a weapon (like the shotgun, which i made shoot out plasma grenades) it does the "exception - gathering data" thing

Anyone know why?

You used the wrong meta in the place of the Plasma Grenade's. Go back and reselect the Plasma Grenade's meta and paste it in the Shotgun Pellet's place.
