ya if you happen to pick the stone up and not kill anything or console it into your inventory, it triggers them to randomly attack you in a town. Pretty funny stuff to be honest
It appears when you pick the stone up and not kill anything or console it into your inventory the next time you pay fine (dont tested if you go to the jail), but it will not attack you if you dont commited a crime. Off topic note: The same happens to me with the guards of Malacaths quest
