I'm waiting for Thurs. before running Fane on any of my chars (fingers crossed), but took the quests for it out of habit. I decided to drop the quest on one char so I could see how the listed rewards change from Eku (assuming it gets fixed). Well, now Eku won't give the quest back and it's showing unavailable until next week.
Now, luckily this happened on my character that has the hardest time with Fane, so half of me is actually relieved, but this isn't proper quest behavior.
