I've been having this happen to me during any mission and it actually crashes the whole game, loose all my loot and its usually smack dab in the middle of a mission....idk what's going on but I'm pretty upset because it happens every single mission. I can't progress at all right now because every time I try to play, it boots me back to xbox home screen and I loose all my progress.
