[Endoperez]

For one turn, you could probably just keep on playing. Most versions only differ in battles. When you view a battle hosted in a different version, what you see can differ radically from what happened. However, the battle report will always show the actual losses/deaths, and unless you try using anything added in the patch (recruiting patch-added creatures like the new Hydras, or the new Mictlan/Tien Chi units/commanders), there shouldn't be any major problems.
