I stumbled upon this bug while working on my project and I could re-produce it twice in blank and my project.
Steps to achieve it:
- Create two blueprints e.g. blueprint A and B
- Create vairable referencing to blueprint B in blueprint A
- Drop it into EventGraph
- Force delete blueprint B (It closes blueprint A)
- After trying to open blueprint A you get editor crash
After crash opening it again doesn’t crash editor.
Crash occours on version 4.7.6
