Over at WPC, our plan was to start the first community game (for those civ veterans, think single player demo game), in the next couple of days. Unfortunately, it appears that we encountered a rather significant issue, and I am checking over here to see if anybody else has encountered it yet. Basically, if you have a save that was made by a person who purchased the game from steam with the babalonian civ, ONLY other people who have that special purchase can open the saves. Even if the game was started by another player who doesn't have the babs, once the person who has that game opens and saves it, it can not go back. From the testing we have done, this is a compatability issue with the saves being made a different way by those who have the babs.
