I finally beat the last mission Midnight on legendary solo this morning and didn't get my achievement. -I beat them all on the same console -I was online for all of the missions -According to Waypoint I have beat them all on legendary solo -But a few weeks back I logged on and my loadouts all reset all my campaign mission reset and had to unlock them all again is this the issue in why I didnt get my achievement. - I would really like to avoid beating it all on legendary again is there other steps I can take? Thanks, CNDA Carcbro
