Dead-end in Mirkwood

I'm doing the Mirkwood quests currently. I heard that this zone is very linear quest-wise, but for now it doesn't seem so to me.
After finishing with the quests in Emyn Lum, I've beign sent to the Scuttledells.
I seemed to finish everything there, but got no vector quest- "whatever", I thought, because I already had a vector to Gathburz from Emyn Lum.
So I finished everything from Gathburz. However, I got no vector quest and the regions of Taur Morvith and Ashenslades are still not completed.
The wiki is really messed about Mirkwood, and I can't find anything there. Any idea what have I missed?
