a few years ago I used to enjoy making custom cards on DB. Recently I looked through some old replays and found some custom cards I made, so I decided to improve on them, but the Custom Cards section seems to be bugged somehow. When I click on the "Upload" button, I get this message:
Error
You cannot upload custom cards.
A similar problem occurs, when I try to edit some of my existing custom cards:
Can this be fixed somehow? It seems like I can upload customs on a new account, but I don't want to remake all the cards I made on the old one to be able to edit them.
