Possible bug in Blueprint editor 4.8.1?

Development Programming & Scripting Blueprint
1

I think I might have found a bug in the blueprint editor. I’m able to reproduce this with new projects.

  1. Create new FPS Blueprint project
  2. Create new blueprint (Actor)
  3. Open it
  4. Save all (cmd + s)
  5. Close the blueprint
  6. Open the blueprint again

The blueprint editor opens, but it’s completely blank. Only the toolbar is visible, and it’s very limited. See attached screenshot. This does not seem to happen if I add anything in the Event Graph before closing it.

Is there a “toggle editor” hotkey I’m not aware of?

This happens when the blueprint is ‘data only’, so it opens up a Class Defaults screen instead of the viewport and event graph. Check under the Window tab in the top if there is a check for Class Defaults, enable it, and you should get the option to open the full BP editor.

Thanks! Would be nice with a short info-text in this scenario!
