I'd be interested to see if the time limits actually have an affect on the AI of the computer. On another note, I've had 2 battles involving towns where 1 unit of the computer routes in the town and gets stuck so every single unit of the AI freezes in place (units from reinforcing stacks as well as original stack units). Until the 1 stuck unit gets itself free to route away the AI just doesn't move. Field battles seem fine and I really enjoy them, but toss a town in there and it turns into a mess.
