Way to detect when leveled actors/guards respawn?

[Seijin8]

I'm looking for a way to do something: detect when a leveled actor with a quest alias attached has respawned or recycled in some way.

 

Example: In the mod "Real Names", it will assign a new name to a character.  If that character is, say , a town guard, then in about a month of game time that name will now be on a different person.

 

I'm using a similar alias system to Real Names in a mod I'm working on and want to be able to detect when the actor under the alias has shifted, so that it can clear that alias and report back that (for instance) "the guard has been reassigned".  I've yet to find a good way to do it.

 

Alternately, I'd be happy if the presence of the alias could somehow "lock down" the actor and prevent the respawn/recycle process from happening.  The only mods that I know of that have tried to do this have instead generated a copy of the original as a new entity to circumvent this behavior.  Thing is: I'd still like the new actor to perform the same roles and duties (packages), and not potentially increase the number of AI running around a city.  I want *that* guard to stay, or to notify when they are gone.

 

Thanks in advance.
