As per title, the Home Sweet Home imperative is bugged. After completing the monument, I see a nice animation with all the dupes happy, then a few shots of my base, then the shot of the monument, and then a black screen (although I hear sounds that suggest that there should be another animation). After that the game hangs and I have to kill it. When I reopen, I can only load the last save, before the monument was completed.
In case this is relevant, the world was started on the main branch before the launch upgrade.
Save file just before monument was complete is attached.
Completed the Home Sweet Home imperative.
