This achievement seems to be broken unless there is something I am missing.
It doesn't acknowledge dungeon quests you had done in the past. That's fine. I don't mind that at all if that's how they want it to work.
However, I just got finished doing the 3 in Stockades, the 5? in Deadmines, and the 7 in Scholomance. I believe that is more than 5.
Is it supposed to say 5 Cataclysm Dungeon Quests Complete? What's going on here?
