After the data loss, i've struggled to configure my world to be superflat. If anyone knows how to make a superflat world with these specs please explain it to me because i've tried for hours on hours. And i keep spawning in with a new default world
Bedrock at level 1
Dirt from levels 2 to 64 (63 dirt blocks)
Grass blocks at level 65
Those are the requirements for my desired world.
Comment solutions please. ty
