Has anybody completely killed off your adversary, occupied all of thier planets and the AI claimed you the victor (I elected to keep playing), but when you check on your adversary on the diplomacy window, his window is still perfect and not broken. I even as a joke sent a message to start trading with them and AI answered. So I went through each of their "former" planets and asteroid belts and found not one single ship on the map. All during my "hunt" to find that last ship, the AI continued to try and give me missions. The other odd thing I found out, Rebels started attacking my planets while I was still trying to find the missing ship.
Now has anybody else ran accross this before?
