This is very intriguing, but at the start of the campaign, there is no such problem in Auscaulis (I just loaded up as eleutheroi and zoomed to city view). I take it that is the one you are talking about. If someone can let us know more about this (what building was it that was looking strange - what city level - what buildings were visible in the city on the strat map view if you can't get the battle map to load, etc.).
