If you don't use this, and use patch 3.27 to Dominions 3, you'll have weird inconsistencies like losing 10 soldiers when you view a battle and then seeing that your army only lost 4. Or seeing one side win when you view it, and then look at the map and the other side's army is sitting in the province.
