I’ve been experiencing something frustrating and quite unique.
Within my playercontroller I’m trying to retrieve the post process volume that is set in the world (get all actors of class) which actually works fine if I access this variable in editor (any of the play modes) but when the game is packaged it can no longer find the post process volume and returns null.
This problem didn’t exist in 4.27 and I have a hunch it has to do with world partition.
