So I was participating in the Double Prize Fight and was fighting against a Valentine with Robocopy Big Band. She hit with me a burst attack, knocking me down and "giving her permission" to use her unblock able, Dead on Arrival. Her PF score was a bit higher so I already knew I was dead. The move finishes, Big Band pops out the curtains and the game crashes before my next fighter comes in. It didn't directly shut off the app, but the game would not continue even after 5 minutes. I exited the app, went back in without closing it, and was left with a completely black screen, with no response from my taps. I exited the app again, closed it, and went back in and everything was fine. But of course, if you leave a battle without defeating all three enemies, the game assumes you lost and my streak with it. Not a major issue of course, but would be pretty annoying if it happens again.
