I have all of my parties upgraded to 20 except for one, and that one is at level 19. Whenever I do a party, I click on the stickers and the Roman Arena comes up (the only one I have left). I have two panels that are pink and the other two are orange, and the same dang corner comes up every time. I had seven stickers earlier today and every one was the same corner! How can I upgrade it to 20 and get my decoration if every sticker is the same thing? It seems like there's a glitch somewhere, and I'm very frustrated. I've worked very hard in upgrading my parties only to have this one stuck at 19!
