You mean he had javelineers instead of a normal general's bodyguard?

- both times, I was besieging a karthadastim city
- the crashes were repeated when I tried playing the battle again repeatedly, but the crashes disappeared as soon as I reloaded but didn't turn on the background script.

Now I got the same message again even when the background script was off. The general had the trait vanquisher of carthage, and the battle was with bad odds for me but won, so it might be an error with his trait when he gains more victories in his quest to collect a triumphus from the senate. When I tried assaulting the city instead of fighting the anti-sally+relief battle there was no crash after returning to campaign map after the battle.
Try following the instructions here.
