In my last game as Sophons I noticed a strange behavior for the ship movements. Lets say there are three star systems connected in via lanes. Two of them are detected and no longer part of the fog of war. The third one is undetected, but belongs to an opponent with which I had been at war and now there is truce. When I try to navigate one of my fleets to the unknown system, the game does not really mention that this is a foreign system but navigates me to the other detected system and from there, it starts a direct way (no star lanes) towards that planet. This takes than longer than the lane that would have been in the first system alreay.

I find this behavior quite buggy because you do not see that the movement will not take the star lane (1 turn) but take a strange different route (3-4 turns).
