On my server, as I cured a zombie villager, my other villager that I imported from another village despawned. I don't know the proper mechanics for him to be 100% living in a house. I created him a house and he never slept. According to the wiki Villagers don't despawn, so I'm confused. Also, about the cured villager zombie, he doesn't seem to be living in the house either. Possibles bugs or unknown knowledge?
