For what it's worth, I tested the new v.73 as Sweboz and played all the way down to 258 BC with just a single CTD. That one DID occur during a battle, but I replayed it twice and was unable to recreate the CTD (which is a good thing). Anyway, in addition to the enhancements, the new version is a LOT more stable (i also played as ptolemaioi and had ZERO CTDs throughout the entire campaign)
