Has anyone had trouble unlocking the Master Chief Saga Achievement? I have been through it twice with a friend, they noticed that 4 missions would get skipped during CoOp, so I went through the game Solo to redo those missions, I finally beat them Last night and no achievement yet. I have 46/46 missions completed it says,
the only thing I can think is that since the last mission I needed was The Heretic in Halo 2, that I need to been at the end of the playlist.

Sorry to hear that this is happening to you. I’m currently playing through the playlist also (normal difficulty one, not the LASO), and am up to Cairo Station in Halo 2. Hopefully I don’t get this bug either with the achievement not popping. You might need to file a support ticket if the problem keeps persisting. Have you tried signing out and back into your live account?
