Teleport script causing random CTDs

[Aintiarna]

The following script is attached to a magical effect that is run by a lesser power. It summons a custom vampire follower I created and works flawlessly 39 times out of 40. 1 time in 40 it causes a CTD and I cannot figure out why. There is nothing relevant in the papyrus logs despite me putting lots of debugging code in (which I've removed for readability). The magical effect gets as far as applying the image space modifier, then CTD. i.e. none of the special effects in the script show on screen, just the imod defined in the base magical effect.

 

Anyone have a clue why it's breaking?

 

Thanks.

You're trying to play effects on an actor but also used EnableNoWait. My experience is that trying to do anything graphical without checking that the 3d is fully loaded either results in failure (but there might be situations where it could cause a crash).

 

Try playing the DLC1VampireBatsReformFXS and DLC1VampireBatsReformBATSFXS effects on the MyBatsFXObjectRef instead of ActorRef. If that isn't possible then try waiting for the 3D of the actorRef to be loaded before you apply those two effects.

I seem to have fixed it but not with that enablenowait. I changed the DisableNoWait on the actor before moving at the start of the script to disable(false) and it stopped the problem. So far. Thanks anyway. I hope it lasts.

I'm sorry it's past so many years, I have a teleport script with pyrotx [/size]Sky Ai Teleporting NPCs at Skyrim Nexus - Mods and Community with him permission, that cause CTD. But your strings script are different from pyrotx one.
