I attacked a city belong to a major faction that started next to me. I suspect it was the capitol because it had a lot of buildings inside. Anyway, the major faction units were still around so I killed them all. The major faction still had territory so I went out and searched it. Couldn't find anything. I tried to execute spy actions but eventually got to a point where I couldn't select the major faction's territory. At one point I tried giving them a gift. That worked! I tried doing some other actions and got a cryptic message saying "you can't do that, but you also can't know the reason why". Uh...
I'm convinced this faction has no more cities. But why do they still show up on the map? Do you have to search and destroy every single remaining unit? What if the AI is hiding that unit somewhere I can't get to or find? What exactly do you have to do to eliminate a major faction? Or is this maybe just a bug in my game? I wasted a lot of time searching for a city that wasn't there
