Uh, scrap all the previous thing I wrote. Let me write it again...
Turn 1280 AD, Indonesia 600 AD.
I wasn't the civilization with the highest population. It was Arabia and it's true.
At the same turn, here's the population of the most populous Civilization:
- Arabia (76)
- China (57)
- Byzantine (50)
- Indonesia (49)
- HRE (40)
- France (37)
- Mughal (32)
- England (29)
I WB some of the most populous cities in Arabia and now according to the population screen, the highest population civ is Byzantine. I then do the same to Byz and the highest population now is France. I then WB the same to France, also England and HRE to shorten the time. The highest population civ now is China. I do the same to China and now the highest population is Mughal. Only after I change the total of my population to 53, I win the #1 UHV. Note that the highest populated city in Mughals was Delhi (12) and after I WB my capital to 13, 1 more of Delhi, from originally 9 (therefore totalling 53) it checked YES.
^^ Notice the order of changes in Victory Screen and the total of all civ population as of turn 1280 AD. I count with calculator so I can't be miscalculate ._.
Note that because this is in the same turn, no more cities get conquer/get conquered. My methodology is by seeing the Victory Screen, Open WB, Close WB, See Victory Screen, Open WB, Close WB and so on...
Also when I'm trying to replicate I got the following error message:
Error in kbdEvent event handler <bound method CvRFCEventHandler. on KbdEvent of <CvRFCEventHandler. CvRFCEventHandler instance at 0x17A2E0F8>>
I can't see the UHV #2 and UHV #3. It only shows partial UHV #1.
Oh, and also, Mongolia died the turn they spawn and I saw a Byzantine Cataphract in Kara Korum that turn. Should also put this in OMG I think...
