So I beat halo 4 on legendary (solo) and although I got the achievement it doesn't register on my spartan career profile. Here's how it happened:
I played about half way through on legendary then my buddies came over. We started another game (co-op) from the beginning and went 3/4 of the way through it on heroic because they wanted to be pansies and I finished it off in legendary on solo when they left. When I beat it it said I beat it in heroic. No biggie obviously I was missing 3 boards on solo so I went back and beat them in legendary and got my achievement I even went back all the way to the alpha checkpoint even though I had previously beaten it just to be on the safe side. Well now im stuck with my profile saying I only beat 7 boards on legendary when its not true and I have all the achievements on each board and the final one all legendary... help?
