Sorry. misread your question. How did i do new locations?

I used the Cosmic forge editor which now has a complete terrain editor that allows you to create a new location which must be based on an existing location template.

However. The Editor is now so advanced that you can delete every single piece of terrain and every game entity from a new location and rebuild it from scratch.

Unfortunately my mod was near completion before the terrain editor and so my new locations are not all they could be.
That said i do no think you would be able to tell which original locations my new ones are built from.
