[Infinite Loop] Workaround for bug causing stuck at loading 70%, 71%, or 72%

Can confirm that, as I’ve had it happen again by accident.

Doubtful it’ll be fixed anytime soon, but at least now I have found a way to proceed:

  1. Roll back to a previous working version of the Blueprint.
  2. Open the editor.
  3. While in-editor, update to the latest version of the Blueprint.
  4. Fix the offending Blueprint and resave it.
  5. Restart the editor.
