Just a quick question.

Let's say I made the following MagicEffect applied to an actor:

.. extends MagicEffectActor npcEvent OnInit()npc = Self.GetTargetActor()RegisterForSingleUpdate(1)EndEventEvent OnUpdate()....do stuff on ActorRegisterForSingleUpdate(1)EndEvent... 

When I save and move to another location, so the actor is detached/unloaded, will that script still run?
Or is it paused and executed again when the actor enters?

anything with a script running on it should be persistent--meaning the actor will stick around until the script has finished updating and running. A good description of the details that make something persistent: http://www.creationkit.com/Persistence_(Papyrus)

Yes but it's a magiceffect with a script. They usually dispel themselves on death, dunno if they do when unloading actors
