I know this has been reported before. I've seen it. How can a game of this magnitude have such a terrible game breaking bug 3 years after release? This is a REFUND magnitude bug.
In most of my walled siege battles where the AI attacks if they use siege towers and ladders they will first push 3 to 4 of those to the walls.. Often times 2 will make it, the others just stop for no apparent reason.. They are not being attacked by archers, they just stop in the middle of the field. At the same time the siege tower units make it on top of the walls and then stop immediately.. The remaining 16 enemy units run back and forth on the battlefield for eternity if you have no battle timer, if you do you just wait until the time expires and the battle results in a draw.
The first time I saw this bug I figured it was a glitch, but now that I have tried playing a new strategy with Rome by playing behind my walls I see it over and over. I reloaded the same battle multiple times trying different things and different settings even tweaking graphics to max performance and the same result occurred. I have the battle saved on video if anyone wants to see it.
Please fix this. This would be a terrible bug at release, much less 3 years later.
