when the villagers got to sleep some times i hear a baby villager's death sound. and in the next day most of the villagers become 'depressed' so one time i was building a house and suddenly i saw a baby villager fell from the sky to the roof of a villager's house and died!
to see the bug.
1: should be night time
2: the house has 1 or 2 beds only
3: turn on F3 + B to watch the baby fall and they always fall on the roof of the houses
4: its very hard to spot but if the villagers are all depressed on the next day that mean you found the bug
