Hi. Just started playing again, and I used to have a script for this, but can't find it anywhere. My current (old) creative/survival test world is close to running out of superflat space, but it's current terrain generator is 100% default vanilla terrain generation. I've reached the "edge" on all sides of my creative "test" area.

tl;dr: Using NBTExplorer, I used to post the template for a superflat world, that's 100% functional for survival bellow-ground (IE, diamonds, caves, strongholds, lava, ravines, etc) under the super-flat surface. Does anyone have such a script (IE "world terrain generation template") they don't mind sharing? Thanks!
