I'm just gonna copy this from another post I made (again
) so I'm not sure if that's the actual problem with this particular game. However seeing as others have completed it I feel like it's probably the same with this one.
As far as I know it's basically the "Done. Unlocking..." problem again. However it only happens for certain games (for me it was Darksiders and Agents of Mayhem). Achievements tend to pop 5 minutes late. Sometimes even days late (had to wait 6 days for Darksiders and 3 for Mayhem).
In FFXV I beat the DLC and the achievement popped 10 minutes later. Same with certain trackers. It's something that happened in the Xbox december update. I had a short back and forth with an ambassador on Twitter but I kinda doubt they're gonna do something about it. The achievements I was missing popped while I was offline/playing a different game. They did have the original date of unlocking though. I think there's not much we can do right now.
By the way "Done. Unlocking..." never actually showed up. Haven't seen that in a good year. But the symptoms are pretty much the same.
EDIT:
So damn glitchy! Help?Another thread with the same problem for a different game. Just so you know it happens to a lot of people.
