There is a link to a map download somewhere in this thread which is still working I think, though it doesn't include the more recent builds. Eventually I'll put all the builds on the same map with Tedit and share an updated version. That won't be for a while though, as I have a massive amount of worlds to move builds from. Next weekend would be fitting to do that I suppose.
edit: found the link
