Ok. So I am playing a custom map right now. There is an asteroid and a planet. The asteroid is so close to the planet that I can see their gravity wells overlap ALOT. Yet still the ships have to use the phase lane and it is pretty funny to watch. You give them an order to move and they move closer to the astroid then start jumping out and they jump away from the asteroid to get to the edge of it's gravity well. I found this out early on and being the ocd me I am gonna start a new game.
