When I downloaded the mod and went to create a world, I saw only the regular minecraft world types.
Btw, the mod version is 1.20-7.4.5

Did you install the Lost Worlds LC mod? The 'Lost Worlds' world type only exists if you have that mod

No, I didn't. I just did tho and now the world type is there. Thanks for letting me know!

One more thing, how do I make a biosphere world in which the world outside the biospheres is a wasteland? I would make worlds like that on RLCraft but I can't figure out how to do so on normal Minecraft.
