First time poster and already did a research on this topic but it seems that no one has a solution?
I completed all spartan ops chapters and got all the chapter specific achievements.
I’ve checked all chapters in the menu and im not missing any chapter on legendary solo.
I’ve replayed a few missions on normal to check if the achievements would pop randomly without luck though.
I did a hard reset with my xbox but still the same issue.
Is there anything I can do to check which chapter didnt register or a solution for this problem?
Im thankful for any help or suggestions.
Cheers guys
