Changes on 10-08-15:

• Private station, moon, or planet blueprints are now automatically set to deny landing from anyone except for the owner when initially created. This should hopefully cut down on those awkward situations where your completed design is approved by a host, moved into the sector you requested, and a random stranger stumbles upon the structure before you even have a chance to close things up.
• Fixed an issue where human defenses in an atmospheric combat sector would turn on their human masters and serve their Praelor overlords. Relatedly, human defenses no longer count as viable objectives in an atmospheric combat mission, meaning you now get an ACV reward if you didn't (rightly so) destroy the human structures.
