[WorldPartition] How to prevent an actor to run script again when loaded second time?

I have an ActorX that runs a script (spawns a different random actor) when being loaded. That ActorX is added to world partition map. And when its loaded by world partition it runs a script (and spwans an object on begin play).
But when player goes to far from that partition that partition is unloaded and ActorX is destroyed. And when players comes back ActorX is loaded again and runs script again (but i don’t want it to run script again).

So how to prevent this ActorX to run script second time. Whats the proper and good technique to process dynamic spanwers/script-runners like that in a big open world.
