Okay, I really apologize if it has been said before, but grenades have been really sketchy for me. I throw a grenade at someone, only having one grenade. I hold it down and watch it being tossed at the person. If I miss, and am on the ground (I could have moved, doesn't matter, I just have to be on the ground) occasionally I blow up, and it says I killed myself. Any ideas what could be wrong?
