Life Story Achievement Broken/Glitched

Games Halo: The Master Chief Collection
1

I completed the Life Story Achievement (The Master Chief Saga playlist) a few months ago but the achievement never popped. At the time, like a lot of other achievements I thought i just had to wait a few hours or so and eventually forgot about it. I am trying to get all of the achievements on MCC currently at 572/700, however I do not want to have to replay this entire playlist again.

A few notes:

  • I completed the entire thing solo. - I have 46/46 on level completion. - I have re-completed the first mission of CE again to see if that made a difference. - I don’t believe i’m experiencing this issue with other achievements including other playlist achievements. - I am not sure if a game update occurred in the time between me starting and finishing the playlist.Thanks in advance for the help.

I too am having the same issue. Played through the whole thing, including the first level twice, but no achievement. I’m hoping the fact that the playlist is marked as completed will be enough that if they ever decide to patch it the achievement will just automatically unlock
