So I have this preset that I want to use:
minecraft:bedrock,48*minecraft:dirt,minecraft:grass_block;minecraft:plains;
and it's supposed to make the world higher, as well as remove villages. But when I put it into the "Generator Settings" box in the "Settings" tab, then delete my world and restart the server, it won't go online. It will say "Starting..." for about 10 secs then just go back to being "Offline".
Is there any way to have this not happen?
