I have played halo 5 campaign on legendary all the way through forever ago, but I never got the achievment. I revisited certain levels, and still nothing. Halo waypoint says I beat it, other accounts show I beat it, and my service record shows that I have them all done on legendary, but my achievment shows I am at %86 and am missing one mission, but I’m not! Also, when I view my best times for solo on my service record, it says I have only beat 4 missions on legendary… where is my lone wolf achievment? It hasn’t been unlocked for over a year. Someone please help!
