Just got the 1.8 update on Xbox One, and I'm experimenting with the superflat editing options.
If you start to create a new Superflat world, go to advanced Superflat options, and then the Biomes tab, there's a Biome called Extreme Hills. If I create a world with this biome, even using the preset "Tunnelers Dream" which has this biome, there are no hills.
What is the effect of the Extreme Hills biome, if it can be applied to a Superflat?

is set; other biomes wont.
