I made a letter where if read it starts a quest, it was working fine for a couple of days and then out of the blue it won't start the quest. Even on a clean save the quest will not start
script on the letter
- Scriptname DefaultOnReadSetQuestStage extends ReferenceAlias
- int Property myStage Auto
- Quest Property myQuest Auto
- event onRead()
- myQuest.setStage(myStage)
- endEvent
this is a defaultscript from the CK with mystage=5 and myquest=0strangersinskyrim.
help is appreciated

_{I still haven't had any luck with it. Is there something I could have done to block that script from working?}

If your script is attached directly to the letter I believe it should be 'Scriptname DefaultOnReadSetQuestStage extends ObjectReference'. It also should maybe be myQuest.Start() instead of setstage if you just want to start the quest

I seemed to have fixed it. After I removed the alias for the letter it was working, but when I give it an alias it stops working. The same thing is happening with my NPC, when he has an alias he just sits there, but when I remove the alias, he uses his scripts and dialogue. So the script wasnt the problem, something is wrong as far as aliases go.
