I wage war. In order to not be a genocider I keep cities. But before I conquer the nation all kept cities turn and then suddenly they're spawning an army equivalent to my tech and if I take one down another revolts in an endless circle. I find uranium in an unsettled area so I settle on top of it but my city revolts in the next 5 turns. All the governors and civic policies that boost loyalty still can't stop the city from revolting. A bunch of AI settles cities near my own and then my city revolts. so... how the **** do you deal with loyalty? Capturing cities without war is fine but making it an impossibility to have resource outposts or no-raze wars is not fine.
