All the villages that spawned in swamps on this amplified world generate with water removed near paths as well as under houses that are a few blocs higher in addition to houses that don't touch the floor and levitate
(seed and coordinates in the attachment - this village was generated in 1.16.1, another swamp village generated in 1.16.2 on the same map had the same problems)
Can't reproduce. Works normally in 1.16.1, 1.16.2 and later.
