Is there something wrong with the autocalc function? Or did something get all mangled up when I installed EB?

I was playing as the Casse, and one of my family members was caught alone out of town by a band of brigands. Being too lazy to play it out, I autocalc'd, and the guy won! It was something ridiculous like 700 guys vs. my 30-member bodyguard.

I guess the Successor's and Karthadastim's bodyguards have the same problem, but mostly because of their insane stats. (Playing the Arche Seleukia, I've got so many family members, that I form goon squads with them and send them about my empire putting down rebels, brigands, etc. Unless there's horse archers, I can usually count on them to win, despite what the odds read at the pre-battle summary scroll.)
