Villages spawning on tall grass cause doors too high, paths flooded, farms raised

Villages are being generated in very buggy ways. Certain times the path is uneven, or the farms are 1 block above the path (meaning you can't get at them). Houses with doors 2 blocks up with no stairs beneath.

Found one on Seed 147896325 at x -247, z 325 that is a good example.

Villagers are also appearing 1 block lower than expected (ie within the path, but moving and not suffocating)
