But it's basically just a few new stone types that are pretty abundant in most locations. So pretty much any land that hasn't been generated will do, and there is plenty of it. Simple matter to either set a Warp somewhere, or decide on a large area that is unused and just regen it. No need for a map wipe, especially as we agreed long ago that it wouldn't be needed.
that is not a bad idea at all just re-render a few hundred chunks to give folks access to the new stuff
