Extended Height

Fixed

• Superflat worlds generated broken terrain in extended-height worlds: the layers ended up at the bottom of the world (around y -256), mixed with chunks floating in the sky.
• The same fix covers chunk generators from other mods that place chunk sections the way vanilla Superflat does. All worlds now generate at their usual 1.7.10 heights; the mod only adds building space above and below.

Note

• Worlds already generated with the bug stay broken, because their chunks are saved that way. Create a new world, or delete the region files of the affected area so it regenerates.
