Start a new map/world,
The current map will be saved and can be replayed at any time, I may also upload it here so that you can play it in Single Player.
It would be nice if you could not put the new map as permanent. FredGnome and I want to make the Eye Of Sauron in the desert and build a new Metropolis in the the desert as-well. You could change the map to and from each day or week.
