well, probably gardibolt has got a point here. i was playing the game basically a couple turns per evening. for a few evenings, whenever i loaded the game, the horde (vandals) would break off their seige of one of my border forts just to return with a new seige in the next turn... but, i guess, it was due to the randome reevaluation since i did not notice the AI breaking off their seiges of my cities later in the game. apologies for the false alarm.
