CrashReporter User Descriptions:

  • EUS Matt.Williams - Accidentally tried to set a montage as the animation for an existing montage section
Steps to Reproduce

1. Create a Third Person Template project
2. Create a montage from the Mannequin skeleton
3. Open montage in Persona.
4. Create one section from ThirdPesonIdle animation
5. Click on the section
6. Under details, you'll see Animation Reference
7. Select the montage in the Content Browser
8. Hit "Use Selected Asset From Content Browser" for the Animation Reference

Result: Crash
Expected: It doesn't accept the anim montage, but doesn't crash
