The following Halo 4 DLC achievements will not unlock for me after fulfilling the requirements several times and on the correct maps!
Ashes to Ashes
Pigs Can Fly
Bird of Prey
The above achievements are tied to 2 of the 3 Halo 4 map packs. I paid $25 for all 3 map packs and want a refund or Xbox Marketplace credit if the issue is not taken care of. I would not have bought the DLC if I knew some of the DLC achievements were glitched. Please let me know what the solution is!
