Im having problems with the Requiem 2 codes and want to know if anyone else has this problem. I want the armor so this is really -Yoink!- me off. I have unlocked the Lone Wolf Achievement and therefore completed the campaign solo on legendary. Yet when entering the code for the Raider OSTT Torso Waypoint is saying I still have to do this. Waypoint is obviously having some sort of sync issue and I need to know how to resolve this.

According to this, you need to complete the second and eighth mission solo.
