I’m playing through the MCC campaign on legendary starting with CE of course. In Halo 2 Anniversary after completing the level arbirter I did not get the mission achievement nor did it say I completed it on Waypoint or the actual game itself. It wasn’t that big of a problem until I started Halo 4 both the leven requiem and infinity did the same thing, no achievement unlocked and Halo Waypoint shows I did not complete them. This time however when I log into the game it self under solo process it says legendary for both missions. Is this something that I am doing wrong? Or just an error in the game?
