MCC Saga bug number 2

So I still can’t complete the maw and the armory I have ran through two times now on normal Saga and I don’t have time to run through again is there a way to fix this saga and I don’t have time to run through again is there a way to fix this so I can get my achievement?

You’re saying you’ve run through the entire MC Saga playlist twice, and both times The Maw and The Armory didn’t register complete? Were you playing offline at any point or co-op with a friend? If you completed the entire playlist solo start to finish, while connected to Xbox Live the whole time, then it seems your save data may be corrupt or something wrong with your game specifically. But I’m not a dev so I don’t know for sure 100%
