I haven't had this problem, but one of my kinnies has.


**spoiler**

After the instance where you take the Uruk to see the Stangard leaders, you have to talk to Gadda after the instance to finish it, outside the Mead hall like all the rest quests there. The problem is that some times Gadda isn't there, nor is his ring. She can see his ring on the mini-map, but not in person (game?). So, she can't continue the quest chain, it sends you to the camp north of the Cuthstan after that.

Not sure why this is occurring. She found the very large npc on the north edge of the Wailing hills and did those quest out of order, so she thinks that may have caused the disconnect. No way to know really. She tried a GM, but they couldn't/wouldn't help. Seems like this is basic game mechanics, and it should be fixed ASAP.
