When I sort my inventory by price, I see duplicates of cards that aren't actually in my inventory. So for instance, I know that I have only one Arabian Nights Mountain, but when sorted five appear. http://deckbox.org/sets/36471?s=j&o=d

If I just leave the standard sort, filter by card name "mountain", and scroll down to see the Arabian Nights entry, it correctly displays that I only have one. http://deckbox.org/sets/36471?f=17bW91bnRhaW4*

Hmm, this was reported on the preview too, I thought we fixed this. Looking into it.

You were right, this was a regression.

Fixed now, Mountain only (correctly) shows once in your inventory even when sorting by price.
