As the Gauls, I watched the Romans build a fort just south of my city of Segesta. A few years later, my faction heir and a small army took over this fort and were in turn besieged there. I couldn't get help to them in time and the AI sat outside the fort until it fell. I tried redoing this a number of times, using the Siege bug, which I have experienced, in my favor. The AI did not lift the siege. After a number of saves and reloads to try this, I finally sent the army out to die honorably on the field of battle instead of inside the stinking fort.
