I've experienced a lot of wierd things when assaulting large cities, I swear the fucking game cheats for itself. I've had ladders that I've constructed disappear, "destroyed" gatehouses shoot at me, soldiers run in every direction but hrough the gate or breach, and have not been allowed to shoot at walls with my onagers. But what really pissed me off is when I had just layed siege to Rome and had ordered towers built. On their turn, the defenders sallied out, all 163 of them, I thought great, this is going to be easy, but when the battle map came up they never came out and I had no siege equipment yet with which to assault the city. I was pissed!
