Scripted rebels

[Tellos Athenaios]

Well if you conquer a settlement the scripted army that is assigned to said settlement should eventually cease to exist. *But* as some poor fellow experienced in his Sweboz campaign: mess with another scripted army settlement and lose -> army comes looking for revenge... (The army may lay siege on your previously conquered scripted army settlement. And if it does manage to conquer that back... Who knows the army you got yourself eventually rid of may appear yet again on your or the AI's following attempt to reconquer the forest.)

EDIT: The thing is... those scripted armies aren't simply guards in sitting duck mode. Internally the principle has been/was/is called Roving General; which kinda explains it pretty well. The army will move within a certain radius of the scripted army settlements... and vanquish everything it can.
