In attempting to purchase 5 black lion keys for 450 gems, I was prompted to confirm the transaction. I confirmed it (5/450 keys). I received 5 super finishers in the mail. If this has happened to anyone else, please confirm.
I doubt there is any chance of me having my purchase corrected, mostly just posting this so that the devs find out about it.
EDIT: I just realized that I was inappropriately charged only 400 gems (the proper cost for the super finishers), so it is more likely that the UI is wrong than that the transaction is mailing the wrong products.
