Hi, so I have played through the playlist on normal difficulty until I got to the mission Dawn. However, I saved and quit, and came back to continue and the game makes me resume on the mission Halo (Halo 1). Now the game says I can continue to Dawn but always loads the mission Halo. I completed the mission thinking it might let me continue to Dawn afterwards but it doesn’t, now I have to play Truth and Reconciliation.
The game shows I have completed the previous missions (36/45 complete). This is frustrating as I want the achievement for completing the playlist but don’t want to have to play through 36 missions again. Has this happened to anybody else? What can I do? Thanks.
