Chapter 10: Echoes of the Dead - can't finish...?

I successfully completed Objective 1 (the Forsaken Road instance). A little video played at the end, and then I was dumped back into Zudrugund but the quest had vanished from my quest log. I know that Objective 2 comes from Halbarad in Lhanuch, but when I ran back to the town, he's not there :(

Anyone else experienced this or have any suggestions? I really wanna finish this quest chain!
