I started a brand new survival world on 1.11.4 and spawned right next to a village
a few in game days passed and i noticed there was only 3 villagers remaining and there used to be around 10-12, the iron golems also have seem to despawn.
I have my game set to peaceful so they could not have died by hostile mobs.
Thank you for your report!
