Since I see that the devs visit this place, here are some oddities I've come across while playing.

* You gain relation if a ship lands on a planet you are near, even if you are at war with the faction the "escorted" ship belongs to, and are actively attacking the ship.

* Vassals remain vassals even if they end up much more powerful than their overlords. This can make it hard to complete quests where you need to make two factions form an alliance.

* "Light Heavy Fighter Bay I" I can see why things are named like this, but it sounds totally wrong.
