I know that other players have already reported about this bug, but I have to register that this happened to me too. I cannot progress in my game because the Joellaut doesn't have the quest symbol above him. He is in fact the character who I supposedly need to be talking with. This problem shoud have been solved since 2014. I was finding my experience with Final Fantasy XIV greatly enjoyable and is sad to be interrupted by such an outrageous problem. I hope I get a response soon and I can go back to my game.
