I have done all of the quests in Kun-Lai Summit, as I have the related achievement for doing all the quests in there, and yet the campaign itself doesn’t recognize it. I have done all the other campaign chapters just fine, and now I am left at 9/10 due to the Summit. There are no quests left to do as neither does the game recommend any nor could I find any remaining anywhere, nor can I find anything by scouring the zone. I have checked Wowhead, haven’t found anything there.
Have you completed Holed up near Shado-Pan Fallback, it worked for me when I was missing kun-lai
I have completed it, yes, I just went to check and none of the cowering NPCs offer the quest as I do also recall having completed it.
