Hello! First of all, I want to thank you for your hard work on JPA!
I have noticed that many of my cards disappear from the market without any members purchasing them after 3 to 4 days of putting them on sale. Is there a reason why? They still appear "on sale" on my card collection list, but they don't appear on the market. I have also tried viewing the market without logging in, yet they do not appear.
The market list just lists the latest 50. We'll make a change soon so that you can find them all. Thanks for pointing out
