TileView Widget Constructing in PIE but not Standalone

Hello. Hoping someone can help with this. I have an actor blueprint that constructs a user widget blueprint and adds to viewport. The user widget blueprint renders its title fine but not it’s sub tileview widgets wrapped in a scrollbox. Normally they populate with a populate box function I created. After several print string tests, I’ve found that not only does the initial user widget not call its construct in Standalone, but that it will not execute the populate box function when called from the actor bp even when it just has a print string hooked up inside.

Things work fine in PIE where the subwidgets in tileview spawn their respective data with EventOnListItemObjectSet and work off data passed through an object to populate the dynamic text fields. I’m just not sure why I’m not getting anything in standalone. It’s the same object reference when I save the widget reference and call it’s function from the actor BP.

If you need any other specifics to help debug, please let me know. I will be keeping at this for a little while longer in the meantime. Thanks

I’ve got it for now. I went and rebuilt the Widget BP that was being created from scratch. The old one looked fine, but it had a persistent stale reference in the populate function that was using a fallback struct structure. It only made itself apparent on reopening the project each time and even when I refreshed or rebuilt the nodes there, while it looked and ran without error, I think that was silently breaking the display as it was the only abnormality with the blueprint.
