Recently I beat the Halo CE campaign on legendary it says on the missions that I beat them on legendary but I still have to receive the achievement living legend as well as legend, on my waypoint it says that I haven’t completed Silent cartographer nor assault on the control room but I have beat them on legendary multiple times. Why won’t the data save and why won’t the achievements pop, (when living legend didn’t pop neither did greenhorn, birth of a spartan, or believe in a hero).
