Hello,
I noticed two items that I have and gotten from the Darkmoon Faire that still register as uncollected.
The items are from the vendor Barum
The two Chain armor items are:
Replica Beastmaster's Cap
Replica Beastmaster's Bindings

Great add on thank you!

The Beastmaster set is sold by Baruma, not Barum.

If you're ever uncertain about an item's source, you can go to Wowhead, go to the item's page, select Links, and then copy the item's In-game Link.

You paste that link into your chat window, which creates what is known as an itemlink. Once you click on it you will see the ATT source path. :)

I think the "issue" is solved
