The mesa biome now seems to have a limit to how the stained clay generates, (15 blocks down from the surface) as opposed to the previous generation being fixed at around Y=60. This affects the mesa Bryce variant as well.

This doesn't visually affect the other variants, but the Bryce looks very bad in comparison to how it did before.

I'm not sure if this is a bug, or intended, but in order to maintain the Bryce's intended look, this should be changed.
