I found another one of those pesky "talk to me again" quests yesterday (haven't had the chance to report it until now).
I was doing my new dragon hatchling, and I got to the part where Kerian wants you to make a Vented Malachite-tipped Dragon Claw (the one with the +5 Dragon Breath).
There's an annoying "Talk to me again!" step of this quest, that isn't really made all that apparent while you're talking to her.
I wound up going down to the wisps before I was supposed to.
Is there a way to remove the "You must talk to me again!" step of the quest, and have her spit out all of her dialogue and send you on your way without requiring a 2nd greet? That sounds much smoother IMO. There should never be a quest where you must greet the same NPC multiple times to get a quest done.
