Interesting! Seems like there isn't a single triggering instance of what's causing it to break then.
When the game froze like that, did the music stop?
If it didn't, I think I have an idea of what might have caused that to happen.
I've uploaded a new build of the game called "BedBugs", and you can click Q. Start from the main menu and immediately try to go to bed. In theory, this should work! If not, I'll keep looking into it, haha.
Thank you so much!
