Well in my case, I’m not using a door button situation; but this still applies to that situation. I basically have a “Game Manager” actor that just holds values and is placed in my persistent level. Let’s say I have an actor in a sublevel that references to the Game Manager publically, I can’t actually get a reference to it unless I use a get all actors of class function and add it to an array and loop through that and get a reference that way.
