Quest Broken: "Find Brother Joffrey's murderer"

[Zed]

The quest triggers don't fire correctly. The last thing in my quest log about the quest is:

"Find Brother Joffrey's possible murderer for Brother Joram in the abbey gardens at Thule Abbey. There was a poisoned goblet in Brother Joffrey's room. Since the Abbey's large library is open, everyone could read about poisonous plants and mixtures."

I have all the journals, the goblet, the flesheater robe from the cultist, but the quest is stuck here.. The abbot is missing from his room, and the governor has no dialog about the beast. I have tried everything, including dropping the quest items and attempting to trigger the dialog. I've gone on to other expansions since I couldn't get any further. Rather frustrating. Any help with this appreciated. If there was a patch that reset quests I'd use it!

Here is where I am in the walkthrough of the quest:

##EVERYTHING BETWEEN THESE LINES HAS BEEN DONE############################################

Once you reach Thule Abbey, you will need to go to the small wooden door to the right of the large gates. The guard there will give you the key to the large gates.

Find and talk to the Abbot and talk to him. You'll learn about brother Joffrey being murdered. You need to ask about checking out brother Joffrey's room for clues.

Brother Joffrey's room is along the outer corridor of the Abbey on the west side. (There's a slight blood stain on the floor in front of the door) Go inside and find the goblet on the shelf. Take it to Brother Joram in the garden outside of the Abbey. Brother Joram will tell you there is hemlock poison inside the goblet.
Find and talk to Sister Pamfila (You'll need 48+ persuade) to find your next clue - Brother Benedetto.Sister Pamfila can be found in the green colored building in the middle area of the Abbey.
Find and talk to Brother Benedetto (The brother out by the cemetery of Thule) He will tell you to make sure you've checked brother Joffrey's room good enough for clues.
Go to brother Joffrey's room and you'll find his journal behind the green painting. (It's to the left of the shelf where you found the poisoned goblet)
Read the journal.
Talk to the Abbot about what was written in brother Joffrey's journal. The Abbot will tell you that he's going to his secret library. Tap the east wall in the Abbot's room until it opens to his secret library. Tap all of the ladders that you see until you find the Abbot’s journal.
Read the journal.

You'll find the Scorpion Flail for brother Jago on a shelf here.

Find the boy Daku walking around inside the northeast corridor surrounding the Abbey. (Not the boy Celso in the center of the Abbey) Talk to him about doing the errand for the Abbot.
Go to the Ankle of Thule area and find Shusanna's house. (South of the garden and west of the cemetery) Talk to Shusanna. She will tell you about her child that was brought to the Home of Unwanted Children. It's the northern part of Eldfell City. (The door on the west side just before you exit the city) Talk to Hartwin.

After talking to Hartwin, you need to find and talk to Father Valar at the Church of the Poor in Shacktown. (East of Eldfell City). Valar will give you Hartwin's journal.
Read the journal.
Go back to the Abbey of Thule and talk to the Abbot again. He will give you the key for the Cult door. (In the basement of the Abbey) Talk to the cult leader about the Beast.

##THIS IS WHERE THE QUEST GETS STUCK########################################################

Go to the governor of Eldfell and talk to him about the Beast.<---does not work.
Go back to the Abbot's room. You'll find Boad the Beast there. <--no beast or abbot.

I even checked the crypt for the abbot. Nobody there.
