And something I forgot to add, when you have the Yuezhi invasion event the stacks(4) move down southwest and surround Chighu, you get a panic mode among the population and the city rebels to eleutheroi, then you have to kill the stacks or you get rebellion again there. After this you have to rebuild the governor house to get things back to normal. Plus when the event happens cause I believe of game mechanics purposes all your cities goes to auto management automatically and you have to turn back to manual all of them again. Crazy and exciting event. Think we may consider this a faction mission thinking twice on that.
