I just experienced that when I attempted to add a Destiny's Child PID. I created the new name, and I added the link, but the PID field was blank, and when I searched for the new Destiny's Child page to find the digits and update the link, it still wasn't showing up. Then I realized that my search menu was set to Non-Sports, and the Destiny's Child PID had been created in Gaming. So I had to go to a different music set, find an unlinked card, and add the Destiny's Child name in Non-Sports there, and then search for it again under Non-Sports, and then go back to this set and update the link.
There are going to be quite a few new names added from the music trump sets that are already here and the ones to come. Is it really going to be necessary to do that every time, even if it could be done slightly more efficiently than I wound up doing it? As opposed to just changing the category for the handful of music trump sets already inputted?
