Sid Meier's Civilization V Patch 2 July 2012

The update will be applied automatically when your Steam client is restarted
2K Games has announced that a new patch for Sid Meier's Civilization V, the latest Civilization sequel developed by Firaxis Games, is now available via Steam. If a user does not have a religion, and receives a religion from another Civ, setting the "automated faith purchase" option could previously cause a crash when the purchase tries to fire for either the player, or the AI. This has been corrected.
Also, if an AI player has open borders and a friendly relationship with another Civ, they would sometimes send a Great Admiral to park in their city. If the city tries to purchase a civilian unit while the Great Admiral is parked there, the game could crash. This is corrected.
