How to fix the "fallback structure" every time I open my project

Development Programming & Scripting Blueprint

Whenever I open my inventory only 1 or 3 nodes with item structure transform into “Fallback strucure”.

  • I didn’t start the project on older engine versions and update. I always stayed in UE4 2.27.

  • I’ve already marked the check box: “Save” within the structures.

I just went deep on the problem and refreshed the “Icon widget” wich was the widget being created. So, refresh all nodes works, among of course with the list i said i did before:

  • I didn’t start the project on older engine versions and update. I always stayed in UE4 2.27.

  • I’ve already marked the check box: “Save” within the structures.

*And now, refresh all nodes in File > Refresh all nodes. Go deep on the fallback structure, refresh everything and see if the problem persists.
