I tried really hard to find it but I couldn't. How do I manage to install a custom biome in an already pregenerated map with World Border /wb fill command?
I mean, I have a 20kx20k map and my intention is to add some snowy custom biomes so I can pregenerate the map until 30kx30k and hopefully to find those new biomes there. Does it work like that?
I know probably no biomes are going to be generated because probably I couldn't be "lucky" so how do I manage to make it appear if the first question works?
