Harvester and maybe other stuff bc i deleted more than 1 mail but idk which cards the other were but that shouldn't matter.
I got the card again but i did relog and so on a couple times
My card just also bugged. I invited someone to trade and at the same time, i deleted my mails to get the card of the ah, the other person accepted the trade and now i don't have the card anymore which was in the mail.
