[Bug from Act IX Chapter 13: The Rising Darkness]

I don't know if i'm the only one with this issue but I was doing the yellow quests from the story and then when i get to the chapter 13 I just couldn't finish the quest "Defeat the Ebondrake and search for a clue". I defeated all of them but nothing appeared. I tried to leave the place and do it again, to relog, but nothing worked. Can someone help me??
