Found this bug earlier today. I was about to eliminate a faction. However on reaching their last city, I found it besieged which prevented me from attacking the city. So I went about clearing out the minor factions. What I found instead was that one of the besieging units was actually inside the city. Trying to attack that unit would instead target the city which would then prevent me from attacking because it was besieged. This effectively prevented me from eliminating that faction. It felt like a bug as I tried everything (incl. waiting many turns) and nothing seemed to help.



I have attached the save game that shows this state. Reloading didn't help. Play as the Vaulters and try to kill the orange faction's last city.
