the F3 menu says it is a plains biome and villages and ruined portals generate on "land". Most of the biome is underwater (not an ocean as sea bed is different and no vegetation or fish) probably because of some aquafier.

Is this a single biome world? If not, does this issue still happen in the 1.18 pre-releases?
