On the Mesozoic valley and Beyond there's a bug where you can rank the speed or payout twice, despite not having enough for the second. This happens when I click fast on it, and the number of cards goes to 0. If, however, you have enough cards to rank it up twice, it will just rank up twice. Here's a video of me doing it in the Mesozoic valley and a funny screenshot in Beyond.
