Hi, I have Halo Master Collection and I am playing Halo 4. I got to mission 7 "shutdown" and I cant resume at where I left off. When I try to resume the game, the loading bar fills up and then a weird sound starts buzzing and the game crashes and takes me to the home menu. How can I resume my game where I left off? I've tried deleting and re downloading and re-syncing the game multiple times. Nothing helps
