Know issues:
-(Fixed in 0.2-beta) Ocean monuments generation is inconsistent, sometimes monuments generate at the incorrect height or place their bounding box incorrectly

-(Added in 0.2-beta) Add flat nether and end dimension

This mod is not guaranteed to work with other mods that add custom biomes, structures or dimensions. It shouldn't crash, but biomes or structures added by other mods may generate incorrectly or not generate at all.
For any problem or suggestion open an issue on github.
