When I go to campaign it shows only prologue on my completed list and I have a continue on requiem. Wtf 343 now you are trying to ruin my campaign experience too. I loaded requiem and still only have prologue unlocked.
I have the same problem.
Had 2 levels left on Solo-Legendary… Was putting it off because I actually WORK…And they’re the longest… Probably should have beat ‘em… I’d have the Achievement… :’(
