Dedicated to Crimson Achievement not showing

Games Other Halo
1

I did all five episodes of spartan-ops and the achievement did’t pop any one else have this problem yet

2

Replay a mission(from any episode) solo and it will pop

3

Play any mission in chapter 5 solo it doesn’t matter what difficulty you play it on (did mine on easy) and it will unlock once you complete the mission.
