Bought Thavairian Mist received Paladin Helm

[Gnarthok]

Not sure where this goes. I submitted a bug report in game as well. I was buying my Thavairian Mist for the +1 relic and upon trying to purchase my second one I was awarded the Paladin Helm from Mythology. Is it even possible to get the mythology tomes back? Or am I just out of luck until I farm up another 600 tomes of mythology? I don't even want the damn Paladin helm.

**Edit: I did not click on the wrong item when purchasing my 2nd one. I clicked on the Mist, got the prompt for Mist and hit accept, and receieved the wrong item in return while still on the page to buy the Mist.
