1) Visible area spots (no fog of war) on the tactical map, beyond my territory, as if there was my ship or base or smth else. I have no any property there but still can see Ai ship movement, its base building, fighting etc.
2) AI freighter stuck on my trade route during the whole game. It does not move anywhere but selectable and appears as "Carrinoids fleet" consisting of "1" freighter (number 1 showed near its picto). By the way, that race did not make any trade treaty with my race and all other ships of that race are active - they are trading, fighting etc.
3) There still appear unselectable stucked pictos of ships previously presented to me from friendly race.
4) I think it should also appear the so called "cross ship" icon near fleets, when fleet/fleet and fleet/base are at the same sector or several fleets are travel stacked as it realized now with single ships.
5) Unforseen consequenses with a galactic event (dont remember axactly but there appear a lot of peacekeeper ships that destroy all on their way). In the description of that event showed that the peacekeeper ships will kill only that ships which owner race is at war and only when its ships are on another territory. Despite of that they swept all the ships and bases of all the races (including peaceful at that time), they killed fighters, builders and freighters in space and on planets. By the way they killed all my freighters on trade routes despite of I had a "galactic privateer" building on my traded planet.
