Quest bugged: The Warchief Cometh (undead)

[UnBannMee]

I got the quest I went to the spot where i was directed to.
Quest started Warchief appeared but Sylvanes wasnt there. So I stood there watching Warchief talking to himself for 5 minutes.
When he left Quest didnt finish i didnt get the reward nor i go the indictation where to go next.
Sum it up. Im stuck with a quest thats bugged and i cannot progress anywhere in the story line.
