Trouble with editor event binding

Hey all, I’m new and have been doing okay in blueprints so far, but I can’t figure out how to bind events to things that happen in the editor for the life of me. For example, I tried binding to OnPreSaveWorld (which I was hoping would allow me to change some stuff in the level right before it saves each time) and I can’t get it to fire in EditorUtilityActor or EditorUtilityWidget at all.

If I go: new project > create EditorUtilityActor bp > bind to OnPreSaveWorld in construction script > place in level > save level

I get nothing. Is there a piece I’m missing? I’ve found a bunch of material on editor utilities but I haven’t been able to find an example of someone binding to events.

Appreciate any help!
