I just had all Loadouts, Armor, Emblems, and Campaign progress reset. I understand more than most how difficult software releases can be (I run the QA department for a software company) but this is beyond the pale. More frustrating than the bugs is the lack of communication. We've all come to expect game breaking bugs from games like Oblivion and Skyrim, but Halo has consistently been a hallmark of stability. You've created something amazing with Halo 4, but the technical issues are a mark of shame.
