To my horror the game crashed on a loading screen during the peasants revolt quest online, so i simply restarted the game thinking that I'd probably start from the beginning of the battle. Sadly no it took me back about 2 hours worth of game play, which made me wonder, how the hell does the auto save work? This completely ruined the experience, this was my first experience of the game (which i was loving) and it crashed and put me back this far to my little rugged village?

I even started getting walls. =(
Can anyone just care to explain to me how the auto save works?
