In my 1.0 Sweboz campaign the Roman would constantly besiege Eleutheroi Messana and so go to war with the Carthies, but then the Romans would be kicked back and Carthage would make a peace with them, only for the Romans to attack Messana again two turns later. This went on for over 40 years until the Messana governor actually died of old age and left the city undefended, apart from a unit of just 2 Akontistai with 3 Gold Chevrons. Must be the first time he actually dies of old age in a campaign.
