AudioTrack destroyed in runtime

Hey guys!

I'm creating timelines from script in ScriptableObject, and I save it using
AssetDatabase.CreateAsset()

But then when I run the animation after manually binding the new timeline to the game object, the tracks are destroyed.

"MissingReferenceException: The object of type 'AudioTrack' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object."

Here's a video that will hopefully clarify the bug.

Your input is much appreciated!
Thank you, Irene

 

This works! Thanks so much julienb!
