Hey guys, I've beaten the entire campaign on Legendary solo and I got the achievements for it... But NOT the Mark IV armor! I went into player stats and it told me I still had 2 mission left to beat. I beat the last mission on legendary, seeing as it was a challenge already, and as soon as I beat it, xbox live disconnected me and I have to play it all AGAIN. Anybody have any solutions or people to contact so i can at least send in the Lone Wolf achievement to get my Mark IV armor? Thanks.
