No its not fixed, not nearly.....in atleast half of my bettles the evemy just stands there and, no wait they do not just stand but they are continusly changing they formation but they do not attack.

One more thing I have noticed is that when they do attack they allways send their archers first but the rest of the army is too far behing the archers so I can usually just charge my calvary and cut them down before their other units start to charge......another stupid bug, dont know if it was mentioned
