So I just spawned into my world, the seed was 8869510684472422104 and close to the spawn was an ocean, well that was what it seemed to be, it was a giant ocean sized aquifer and if you press f3 it shows that the biome is in fact a plains biome. Now this caused some weird terrain generation for example this village that spawned in the middle of what seemed to be an ocean. This makes the generation look really weird and a raid in this type of village would also be quite boring
