Hello my friends.
There are other oddities in Skyrim and CK:

The "trivia"

- I've made a quest scene for 4 ghosts unique actors
- Initially they're in a custom cell used for "service" (it contains all my custom NPCs and they're moved on request).
- You know, for the scene, I must use the Aliases, so I've made 4 different aliases.
- The trigger volume used to start the scene works as here:
---- Each ghost is moved on his xmark to another cell where the player is.
---- Every moveTo() is followed by an explosion effect placeAtMe() on the xmarkers
---- doing an utility.wait(1.0)
---- Starting the scene and it is:
-------- Phase1: Each ghost walks to another xmark (different for each ghost)
-------- Phase2: Each ghost cast a targeting spell
-------- Phase3: Scripted -&--#62; Moving back to the service cell by doing MoveTo() and explosion PlaceAtme()
---- Scene ended here

What's going wrong:
- If I'm using a fresh new character and doing all the mod walkthrough it working everything
- If I'm using a savegame (started since v1.4 of Skyrim) and doing all the mod walkthrough, Phase1 and Phase2 are not working. Phase3 is working
- My friend have tested my mod by doing all the walkthrough with his character and everythig worked fine.

Let's discuss on this!

I've initially used ReferenceAlias property to move my NPCs. So I thought to replace these property by using Objectreferences instead of ReferenceAlias. I got the same issue as above with both methods

:-P
