I still have the achievements and it shows i completed campaign on my service record, but it only showed the first level and i would have to play the game all the way through again to open up all the levels at this point. I have restarted my console multiple times and the levels will simply not show up. This is clearly an issue that should be resolved if this has or does happen to many players it is a big drawback from spending the time to beat the game in the first place. Still an awesome game though. Please help.
