After playing through the entire Master Chief Saga Playlist on MCC, I come to find out that two missions didn’t count. These missions are The Maw and the cutscene Heretic. I went back and started the playlist over and played through these missions again. After completing the whole campaign of Halo CE for the second time in about a week, it still didn’t count these missions as completed!? That was a lot of time for it to just poop out on me like that. I wonder if there is a way to fix this.
