So I beat the Master Chief Saga playlist and it said for some reason I didn't do The Maw and Heretic and had 44/46 in the playlist done. Which makes no sense as you can't get through the whole thing without doing those but whatever. So I go all the way back through CE and the beginning of 2 in the playlist and am now at 46/46. This happened 3 hours ago and still no achievement pop up. what's going on?
