UMG 3D Widget in Sub-Level disappearing on saving

Steps to create the bug:

  1. Create new Widget file fill it with
  2. a basic square / text / stuff for
  3. visibility Create new blueprint
  4. “widget placer blueprint” add widget
  5. component to the blueprint set class
  6. to newly created widget place in a sublevel (you can now see the widget in 3d space in the editor)
  7. hit the save button

this will make the widget vanish until it is manually moved again.

Is there something i missed why this behavior is occurring?
