I seem to remember in a live stream it was said that although we are always in a state of war with free cities, they would mostly play defensively and just protect their own territory. That has not been my experience. In several games now, I have been able to flip cities to free and then the turns begin to count down until they will join my civilization. The thing is while waiting for the free city to flip to me they spawn a bunch of the latest tech units and move into my territory and start attacking me. I almost always end up just capturing free cities even if they are going to peacefully flip to me soon because otherwise they will keep sending units against me which means I have to leave my troops there anyway. Anyone else seen this? Is this working as intended?
