I have no idea then, I will try to remember to watch for this during my battles and if I find I do have the same problem but have not noticed it I will tell you. I played a battle with more cavalry than my usual today, I used Praetorians, Armored General and Legionarry cavalry to back up my large infantry line and do not remember experiencing this....

I will test it, but just in case 1.2 fixes this do you have the patch?
