I’m sorry but I have no idea about how those parent folders work, I find them very confusing too! (Actors seems to appear anyway if you move them into different folders of the same level, so I really don’t know what they are named after)
I think that there should be a “uniqueness check” when an actor is created (and even if there wasn’t, the string is so long that it’s pretty hard to get the same value with a random generation)
