I forgot to turn it off. Once that was indeed very usefull. In the campaign I was attacked by a larger army, still I was pretty shure I'd win. But before I knew it most of my army routed, I brought all of my reinforcement (4 "green" vikings) wich chased the pursuing attackers away. Next thing that happend was the AI brought fresh troops at the far end of the map - easily enough to beat me - but what did it do? Yep, took position on a hill far away and stood there, not doing anything. If the timer had been on, they'd probably still be standing there.....
