I was beseiging Larissa and decided to attack. I had a force of some 600+ guys and Larissa was defended by about 50+ (the remnant of an army that was recently defeated). I built 2 seige towers and a ram and assaulted the walls.
Strange thing was that my seige towers reached the walls and then the door to the tower opened, however, when the soldiers inside walked off the platform onto the wall THEY FELL THROUGH THEM TO THEIR DEATH! WTF? It was kinda hilarious to watch, but two units of men died this way. as soon as they walked off the platform "YEARGGGHHHH!!!" Like they were Howard Dean or something.
So I reloaded the game and tried again, with the same result. No way!!! So I reloaded attacked the city again and used auto resolve to win the battle.
But I ask again... WTF? huh? WTF?
