Has any one been able to create any thing with the map editor?

I have found that resaving the map after each edit, or closing down the editor and reloading after an error message kicks in gets rid of all those pesky range check errors. Oh, and as someone here has mentioned before, if you want to edit the names of the planets in a system, you also need to keep the roman numeral after the name to avoid range check errors.

All I have done so far with the editor is to build a fairly accurate Sol system on a random map.
