Summary	09166: imago: game can softlock, no enemies left to kill, no progression
Description	I encountered a softlock in imago during a livestream ?si=qUyiQfzQmbRNRubK&t=3437 I have a feeling it's just a bug in the game, but given the severity of it (would require the cabinet to be rebooted as there's no way to die) I'm logging it here. Haven't managed to reproduce it since, nor is it clear from the video what might have triggered it.

No.23256 Haze Senior Tester 12 days ago	hmm the link to the specific position in the video didn't work, imago gameplay starts around 52 minutes in though, and the final enemy is killed around 57:24, at which point there's no way to progress that I can see.
No.23261 Robbbert Moderator 8 days ago	After watching the video we can say the problem occurred on Round 6. Also, the player's score got corrupted. There's no save state or inp supplied, most likely because it couldn't be replicated. So, it's been acknowledged. If anyone has something to add, please do so.
