Some villagers tend to sleep on the floor, and even under beds instead of on beds.

I used to tolerate some of them doing so, but everyone's sleeping on the ground this night, so that may be a problem.

The villagers don't sleep on the floor every night and the screenshots are captured on a specific night when so many guys do this.

I haven't recreated this error in any other world, so this is my world, in case you need to look further into the issue: https://hanoi01-my.sharepoint.com/:f:/g/personal/0132549206_hanoi_itrithuc_vn/EmW2GE_ZduFJkXvDIEe-apoB5QEbPw9S_t8dc61ieO9_tg?e=wsJpEi

The suspicious villagers are at -43 52 -29, in the basement of the house which has a cow-pig-sheep farm attached to it.
