The Taming Gift Set procured via the Kiel Hyre Quest mid-game as a reward is bugged.
Clicking the item gives another copy of a Taming Gift Set... clicking the item several times gives the same result.
I asked around RT and turns out this is also an issue for other players who did the quest. Most simply keeping the reward in their inventory in the hopes that the bug will be resolved somehow. I searched around the forums and there doesn't seem to be a report about this specific bug for some reason.
Hopefully this gets resolved.
