So the geniuses at 343 released the update that wiped a lot of people’s singleplayer saves out. I was in the middle of a legendary run when the update hit, so my first two levels were wiped. I finished the rest of them on legendary today, and in my mission select screen the first two missions are shown as locked with the rest completed on legendary.
When I beat the game on legendary, I got no achievement. Oh, and I didn’t get the legendary ending, either. I’m hoping/assuming if I go back and do the first two missions again, the achievements will unlock. Anyone know if this is the case? I’m not going to bother if not.
