The SS buffet happened to me as well. First three weeks I started playing, SS and C were the two spots I could not fill with anything, even a "Special edition five star". Had two four stars at each slot.
Anyway, I pull Semien that weekend. 420 Prime. I was stoked. I max him out, then an hour later I pull Legend Banks. LOL. Later that weekend I got another SS, just don't remember who it was.
The sticker boxes are cool they’re like emojis for our forums
