Why have there been so many problems in halo 4 war games. I have had problems since day one. like getting shot threw walls, me shooting people in the head with a sniper and them not dieing, hitting someone with sparton laser and it just takes there shield off, my load outs have reset 3 times already and my challengs reset once. there has been alot more things that is just insane im just giving small example of things. im just wondering why these things are happening
