Makes savannas generate flat — wide, level plains like real-world savannas — by gently lowering the hills, domes, plateaus and shattered terrain that vanilla scatters across them, while leaving the rest of the world exactly as vanilla. The result is open, buildable grassland that still looks naturally generated.
