Editor crashes when saving multiple blueprint defaults

Development Programming & Scripting Blueprint

This seems to be easily reproducible:

  • Select two or more blueprints of the same parent class in the content browser
  • Right click and “Edit Defaults”
  • Change a common property (such as Hidden in Game)
  • Save by clicking on the “Save” button
  • CRASH (writing to null pointer in FEngineLoop::Tick() Line 2080

The crash only occurs if you save via the button in Edit Defaults. If you save all, or save them via content browser, it works fine.

Hey Veggiesaurus-

I was able to reproduce this as you described in 4.4. Luckily it has been fixed in an internal build and will be reflected in a future release of the engine. Let us know if you continue having this issue after the next update and we will be happy to investigate further.

Cheers
