If the player is holding Up after breaking the Capsule at the end of Act 2 and keeps Up held throughout the results tally, their character(s) will not continue to the right during the transition cutscene and will continually look upwards. This cutscene cannot be skipped with Start, so the only way out of this is to restart the game.

Not fixed in any version.
