Zombie audio files after game exits

I have an audio folder with a few wav files that are loaded in C++ using LoadObject(). After some recent changes, after I press ESC to exit the game in the editor, that there are zombie audio files that are empty called “None” in the content browser (which disappear if I quit and reload) - see image. I also cannot load the audio files if I run again till I restart. Any ideas what causes this?

Additional info: when I create the audio files, I use UObject::AddToRoot() to prevent GC. When I tear down, I call UObject::ConditionalBeginDestroy(). If I take the latter call away, the zombie files don’t appear. But won’t I be leaking memory, or does the root set get destroyed at exit?

did you tried calling RemoveFromRoot() before remove attempt?

I shall try that this evening. Thx!

OK sorry about the delay in getting back, so busy around here… It wasn’t RemoveFromRoot(), it sort of stopped happening to my audio files when I remove the teardown code (ConditionalBeginDestroy()) but now it’s happening to my particle systems. Could really use some help on this, Epic?
