Right now I am playing great plains with Louis to get a quick cultural victory (I am trying out different leaders for this). With the massive culture I am acquiring a city flip is certainly not out of the question. So at one moment I flip a city from Hannibal and I examine the city. To my astonishment I have the heroic epic in that city. I didn't build it yet. All other culture buildings were gone after the flip but the heroic Epic stayed and even said +4
Is this a glitch? I never ever captured a national wonder, so how is this possible?
