Unfortunately that screenshot doesn't exactly help in pointing out the bug...not enough info to go on.
Also, Frenzy mode. You know how, when you set it to Single Powerup, there's supposed to be another card spawning once whoever picked up the last one either uses it, loses it, or throws the shell? Well that doesn't happen, now it acts as if there's only supposed to be a single card for the entire round. I think it doesn't record it whenever a player picks up the card or when they lose/use said card. At least...that's what's going on at this end.
