Shogun 2 AI problems

[Pc.robb]

Is there a AI patch or fix for shogun 2 total because all the AI does in battle is wait near the edge of the map for me to attack, they don't move or anything.

I bought it yesterday and so far i'm not impressed with it :s

I have it on steam and I checked for updates, says it's up to date yet there is still problems.

EDIT:Hi simon, thanks for the reply. I'll definitely gonna have to look into this mod thank you.
