Hello, we are playing one world for some time already, but I don't like that there is no plains biome anywhere close. I was thinking if it was possible to use some editor to make some part randomly regenerate. Mabye it's nonsense and only the whole world can be regenerated? I don't want to bother editing the world by hand and make it myself. I want something like: here this area from here to here, make new. Possible or not?
