Another rather important bug with regards to when the AI has reinforcements during an assault of a city.

Basically, the AI reinforcements (i.e. second army) won't do anything if they haven't brought their own siege equipment and the walls/gate aren't broken. They simply remain stationary even when the initial attacking army has been routed or withdraws. They just sit there. Unfortunately, I play without the timer on and unless I decide to go out and meet them (i.e. sally forth), I essentially have to ESC and quit the battle simply to continue the game! I was astonished when this gave me loss considering I was the defender... not only this but I also lost the city!

Very bad. :(
