I'll try to be cautious to not spoil it for people who are about to play it, but basically.
The quest was bringing back the villagers. I was in the middle of that quest when in the 9th day out of nowhere the surprise happens and no matter I do it or not, I can't finish the villager quest afterwards. And since it saves in the night, I didn't think that'd be a point of no return for the game and got locked out of it because I saved in the same slot.
Of course I could still follow the story as normal to the end of the chapter but I kind of left feeling bad because I wasn't able to rescue them all at the end.
I would suggest triggering that surprise once the villager quest has been completed so that people don't feel like it was a left out story plot.
