Pandaria/Dread Wastes Crime and Punishment Quest Bug

The quest “Crime and Punishment” of the Dread Wastes campaign in Pandaria is still showing on my map despite having the whole campaign marked as complete. When entering the cave where the questgiver should appear, nobody is there. When checking my campaign progress with the BTWQuest addon it shows that quest as not being completed despite all the succeeding quests being complete.

It’s been quite a while since I’ve done this campaign so I can’t remember if I’ve actually completed the quest and it’s bugged, or if I did something to somehow skip this quest and it still shows on my map.
