[I Broke a Quest?] Old Friends ( Goblin Quest)

So when you kill the giant turtle, you take a flying machine to go and meet Thrall.
When I reach my destination, I notice that Thrall fell thro the map.
Now I can't turn in my quest.
I tried to relog, and noticed he did the same thing.
When I went to where hes suposed to be, I fell too.
In fact, I keep constantly falling if I go too far from the camp.
Am I bugged, or it's just a know bug with goblin area?

Apreciate if any GM would answer my ticket/solve my problem.

Thank you.
