I conquered some capitals and other cities. I had gone Order and Liberty so the extra cities didn't hinder my overall happiness. After normal turns of resistance, they seemed fine. Eventually, I annexed one capital. Denmark wiped its previous owner off the map and out of the game. A number of turns later, my captured cities all went into resistance. The former Greek cities stayed at single digits remaining but never moved from that number. The former Egyptian one had the turns grow and grow, at one point reaching 935 turns of resistance. I have no idea why and they even had WLTK days. Can anyone clue me in or was that a bug?
