Cannot access Titan Hard Mode or complete Relic Quest

For the past week I have been having an issue with the Titan Hard Mode quest and a Relic Reborn quest for my Bard.

I am on the step of the Titan quest where I have to attune to the aetheryte in La Noscea. I have tried 5 times to attune. It completes and shows the "quest complete" window, but the duty finder never updates and the quest never completes. I am unable to queue for Titan and cannot complete my relic quest. I have a ticket in and have received no response. Please help!

Another guy I know had the same problem and his full inventory caused it. Although nothing really lands in your inventory, you need to have a free slot to finish the quest.

Yeah, that was my problem too. A relief to know that it wasn't a more serious issue, but definitely a bug to be worked out.
