Halo 4 Legendary Co-Op stats didn't track?

I am not sure how this is really explainable. We had a group of 4 Players in Co-Op Legendary as I had just received the game in the mail finally on 11/10 (Saturday) and we sat down to do the whole campaign.

We all were in it 100% of the time and we all got the achievements and such but one of my friends has his progress glitched? It shows all his missions complete and such which I checked his online games played and they all show up as complete but you go in game and it says “Total Missions Completed - 7” his time played also is a bit different. We were all there keep in mind.

His time played shows “4:10::50” while the third person shows “4:47:46” they both like me had just started while in my lobby before that it read “Time Played - 0 days 0:00:00”


Is this happening to a lot of people and how would we go about fixing it? We only took two breaks between missions 3/4 & 6/7 the “/” being the place we took a break. He does have all the achievements and all the terminals found as we somehow managed to do those all in one play through by accident.

It isn’t a main concern as we will more than likely play it again (I know I will) but he really wanted to get the Raider Armor from Waypoint when the others were doing it last night.
