There has been a small bug-fix pushed-out for Civilization V. Not sure if its live in steam yet, but will be very soon. Issues fixed include: Game now runs if user path includes special characters. AI will now make gold per turn deals in amounts other than 5 GPT. Open borders is canceled immediately if war is declared and troops in enemy lands displaced. AI valuation of cities in trades and peace deals improved. Unit maintenance now scales appropriately in Time Limit games. Various crash fixes. Thanks to Ed Beach (Lead Gameplay-AI Programmer for Civ5) for the info!
