Bug report: Quest

[sabbe666]

What is the bug? A quest

Is it a spell or database issue? (database relates to any NPC, quest or item)
it's related to an NPC in the quest

How can you reproduce it?
I don't know the reason or something , but I really want the head item from the quest reward.

Please describe, in detail what happens when it bugs up, and how it's malfunctioning:
I did the Teron Gorefind quest line, and the last quest "Teron Gorefiend, I am..." is bugged.
I take it from the ghost npc, but nothing happens afterwards - I can't fight the draenei that spawns there - he's "green" to me - I don't get to be Teron Gorefiend or anything - the draenei spawns, and after a few sec he disappears. Nothing Else changes.
