I have completed the Kun-Lai campaign and earned Slum it at the summit, but it’s not been marked as complete on the Pandaria campaign. This is the only thing left for a 10/10.
Looking on wow head quest completion tracker it might be The Shadow Pan quest at fault, but I am 100% sure I have completed that as I have also completed follow up quests
This affects me and also my partner as we’ve both been questing together.
They have an alt, which was able to complete the Kun-Lai campaign after us, and that was marked off on the pandaria campaign.
