I have collected all 8 Iron Lord Artifacts and have not received my achievement for doing so. I have been waiting since before challenge mode for wrath of the machine to receive it. The link above provides proof of my collection of the artifacts. I have also attuned them on all 3 of my characters, I have taken every step that I could think of to fix this issue but nothing has worked and I am tired of waiting. My gamertag is LongRangeHands.
