Village generation is absolutely broken

I'm sure everyone has seen this in normal worlds, but generating a village results in areas being cut out of the terrain, houses spawning in the ground, paths being placed under grass, paths outright floating, buildings basically having their own platforms, paths jumping straight up instead of sloping, parts of buildings floating off the ground, water and farms spawning in the sides of houses, and probably more! If we're reaching the final bug fixes of 1.14 this needs fixing now. It's been left for too long.
