The last game I was in was a game of headhunter on pinnacle. During this game I was holding 10 skulls, however the achievement didn’t register. I proceeded to deliver these skulls, hence winning the game. However the achievement still didn’t ping. In the match report it said that I held a maximum of 10 skulls.
I do not own any of the dlc for reach and I would have thought that that was the reason I didn’t get it. That being said however I have unlocked achievements from other dlc’s without getting them.
Any help would be much appreciated, as I’m rather curious about the way dlc achievements are awarded.
