Previously there were two types of "Perfect Jade". One was received as a quest reward in Celestia. Many of you noticed that the reward one was 'buggy' in that it didn't have card art, it didn't work with the recipe, and it didn't stack with the other Perfect Jade. It was, in essence, garbage. Those of you who did not sell those Perfect Jades, now have 'Vendor Trash' in their backpack instead of those broken Jades. Just sell it at any regular vendor (not Bazaar) for 100 gold each.
