When villagers walk through doors, they are supposed to close them.  Instead, villagers do not close them roughly 50 percent of the time, leaving them exposed to hostile mobs during night.  This affects all worlds, and I only experienced this after 1.19.3 was released.

1. Go to any village
2. Wait until night time, or place a job site in a house with a door
3. Either they will not close it upon entering, or won't close it exiting.  If they close it both ways, try again, it will happen about half the time.
