TPF Alexis said: In my experience, it tends to happen when a Countdown takes out a goon, and that goon's Countdowns were the only enemy Special tiles out, which then causes Circuit Breaker to go off. Possibly related to the similar bug that sometimes crops up when America Chavez takes out the last enemy with Ticket to the Multiverse.
