The current logic is to spawn a hidden Actor which holds a struct with customizable side quest variables like title, description.
They should get pushed into a widget at BeginPlay, but only the title, description and reward, which already have a Binding in the Widget. (this picture; description from the struct):
So, this happened. I removed the ListView and just added the widgets as “Add Child” either into the Vertical Box or the Scroll Box and the struct is passing fine.
