Hello need some help on a couple of things.

My mod concerns two competing messenger businesses with outposts in all of the main cities. These businesses are in competition which spills over into open bloodshed. My questions are;

1)How can I reset stages and objectives to represent who owns which outpost. For example, Messenger A has an outpost in Falkreath. It is attacked by the player on behalf of Messenger B and the ownership changes. When messenger A attacks again and regains the outpost, how do I inform the player they need to recapture the Falkreath outpost on behalf of messenger B? I can't figure out how to reset stages and objectives. Also, if the staff have been killed and "disabled" how do I reset them to "alive" so if it's recaptured they can resume their duties once they're enabled? At the moment when the outpost is recaptured and the staff re-"enabled" it enables their corpses with no clothes on

In short, all of the outposts can be owned by either Messenger and can change ownership many times. Only when the faction the player has allied with owns all of the outposts can they mount an attack on the HQ of their opponents. I need to keep the player informed of which outpost is owned by which messenger service and update the Objectives/Stages and this means repeating objectives/stages. I've looked at the Civil War Scripts and it simply baffles me.

2) How can I ensure the "enemy" messenger service can assault and take over the outposts without having a sprawling script. My first thought is something like this;

A trigger inside each outpost to start a timer when the player enters. If the player hasn't visited for a long time, the enemy attack the outpost by silently killing the staff inside the outpost and capturing it - Then inform the player through an Objective Update or even courier note to say the outpost has fallen. Can I put these triggers to call one big script to control all of these ownership issues? I think Papyrus works better by having the same small script run ten times rather than one big script to do it all, but which is the best way of keeping track of everything?
