1. Create a new single player game.
2. Admin scan outcast territory until you find their homebase sector and them admin warp there. (this is the best chance of seeing the bug, the outcast have more turrets)
3. Wait next to an outcast station for some defense fleets to come and go
3. Open your navigation panel and sort it by name. As soon as a defense fleet gets in loading range the ships and undocked entities will be listed in your navigation panel. The problem seems to happen as the ships enter loading range.
