As I remember I doesn't happen in case of a friendly race.Deceptive races have no special behavior in this situation.
Do you mean that every other race type will trigger the combat screen (every turn), which is annoying
If so, yes, it's really annoying, and it's in my list to do something about it.
Yes, F2, choosing other system (a distant one), F1 and the screen is centered on the first system.You mean when you are in the Colonies screen (F2) and switch colonies by using the pulldown selector
I can look into that.
Edit: in all those cases the attitude of minor races were neutral with no reason of worsening.
