Recent Civ5 patch breaks save games

[eyebiter]

FYI - The changes made with the new multiplayer and Pitboss functions for Civilization 5 will break previous save games and mods.

Started a  new vanilla game after the patch, the issues did not appear (spinning globe cursor, hangup on diplomacy screen).
