Hi! Thank you so much for playing.
I'm really sorry you encountered a bug. Yes, as you suspect, a video should play at that point. That bug has been reported to me in the Mac version (which is why I couldn't release a Mac version), but no one reported it in the Linux version, and the tester I have didn't experience any problems.
What resolution and screen mode are you playing in? You can try adjusting those settings and see if that fixes it.
