Immortal Flames quest loop

Time: 11:15 PM EST
Frequency: Unknown (Twice in a row)
World name: Lamia
Character name: Tama Softpaws
NPC name:Willielmus
Monster name: None
Class/Level: Dragoon/50
Party or solo: Party
In-game time: approx 7PM
Area and coordinates: Coerthas Central Highlands/The Aurum Vale V15-H35
Steps:
1.Collect quest Gilding the Bilious(Immortal Flames)
2.Speak with Willielmus outside The Aurum Vale
3.Enter The Aurum Vale using the Duty Finder
4.After completing the dungeon, the quest reverts back to step 2.
5.If you speak with the npc again, he gives the quest to enter Aurum Vale again.
Abandoning and re-completing had the same results.

Entered the duty finder with 3/4 in party before hand.

While I'm not having exactly the same problem, I am frustrated.

I just completed the Aurumn Vale and went to turn it in to Swift.

Except nothing happens. He congratulates me, I get the big words on the screen QUEST COMPLETE and it shows up in my chat log, but the journal doesn't update and I can't increase my rank.

I don't get it.
I'm on Balmung.

I've added an image to help.
It clearly shows I've completed the objective in the chat log but my journal won't update. No matter how many times I talk to him.

Edit:

I couldn't progress for the entire day and then just a few minutes ago it decided to work. Weird.
