Heres one for you me and a friend have been playing Halo on Legendary trying to get through it almost to an end of a mission when the update pops up kicks us out and goes straight to updating after it completes it goes into Halo Channel and then I have to back out of that then it goes back to Halo Game Title Screen so we lost all out progress if we try to restart at our last checkpoint we cant because Halo makes you start a new mission when you try and start co op.
