If you've created a mansion, or about to, and/or it needs to be updated from someone finding a bug in the mansion, or you added a bunch of rooms, you need to do one thing before sending the update to the admins. From the time you start a mansion, it will have the name of the mansion in the "Mansion Info..." tab in the menu in the editor along with the version number there. The first version added will be 1.0, and the first update will be 1.1, and so on.

Thanks!
