This quest is half-bugged, because of the cross-server mechanic.
I was having a problem when I was doing my Golden Lotus dailies with a friend off of my Real ID (he was on Stormrage, I'm on Khaz'Goroth) All of the quests from the first hub went smooth, but I wasn't able to target the Quilen.
I realized quickly, it was because I was in a group with him and I got transported to his server, so it sort of glitched out, because his server didn't have that quest, my server had this quest, while his server had the 'Kill 6 Mogu Effigy' quest.
I simply dropped group, ran out of that specific area (to allow it to reset back to my server) and everything was able to be targeted and completed. I just did that one quest solo to ensure it wouldn't glitch out again.
I hope this helps anyone who is experiencing similar problems.
