Any villages discovered have weird gen issues, fractured villages, going up and down on levels. On top of that, there's only one villager spawning in any of the villages I find. Note, I am playing the regular version, not insider beta - but I do have experimental features enabled.

In the last picture, with the water, I noticed there was 5 or 6 zombie villagers in the water. Perhaps because of the world-gen bugs, the villagers are being spawned somewhere outside the village and being transformed into zombies?
