Well, cos of storymode has no ironmode, im on the saving way... i only lost 2 fights so far, one was the fight around doccina, where i load an older save, the other one was as i raze a village and a king with his vasall added me in cos i couldnt break the raze like vanilla. i loaded there too...
But i think i constant loose some renown for decisions i made... but it falls war to fast.
RTrue is that with my 595 men i couldnt loose much battles, but i didnt gain much for robbers etc. since im still so strong. I didnt fight much with factions, since i allways sell first my slaves around for money...
