[Bug] Quest item "Chimeral Inscribed Ultimatum" has failed to drop

Hello there everyone

I am just making this post to inquire about whether anyone else is missing the quest item that drops from Xyclucian, as I've killed him three times and to no avail has the quest item dropped for me, and well of course I can no longer continue my ascension quest properly because of it.

I also lost a quest item. We were at a party with a friend. Everything is fine with his subject, but there are problems with mine.

Same here.
Loot disappeared after trying to loot it. Quest is updated to "Place... ... in the Temple Offering".

Update: Killing again the boss does not yield the item.
