I downloaded the newest version for vanilla and pick Egypt first. The scenario goes well until the Arabia civilization is rising. Two of my cities want to join Arabia, but I say no
The next turn the game asks me if I want to take control of Arabia, and I say yes. Then something strange happens. Two of my cites become ruins
But I can go into there city screens. Is this the correct behavior when I take another civilization in game
