In 4.23 you can try the EditorUtilityActor class, because the Placed Editor Utility Base was deprecated. It seems to tick in game… But it doesn’t tick in editor like the Placed Editor Utility Base was. Maybe that’s a bug or unintended change, because we can’t get the in-editor tick working anymore.
I’ll probably submit a bug report for 4.23 regarding this, I just hope it’s not a deliberate decision to turn off in-editor ticking for editor utility classes.
