Hey, thanks! But there's a problem: The aqua biomes don't seem to load properly.
I used a command to search for a mushroom fields biome. Those are always supposed to be islands surrounded by deep ocean. However, when I teleported to the biome, it was surrounded by grassy plains. When I pressed F3 to pull up the debug menu, it still said the biome was "deep ocean," but I was standing on solid ground.
My random seed is -6817391374897860619 and the mushroom field biome I am currently located in is at coordinates -1461, 63, 1413, if you want to check to see for yourself.
