Description

Crash when Child Actor Component, that is set to Destroy Other Actor on overlap, overlaps Parent static mesh inside of the blueprint editor

Crash Reporter:

[Link Removed]

Steps to Reproduce

1. Open the attached project
2. Open blueprint 'BP2'
3. Open the Viewport tab
4. Drag the Static Mesh cube into the Collision Box

Results: The editor will crash because the child actor component is destroying the parent bp

Expected: Although this isn't the correct way to accomplish what the user is trying to do, we may want to handle this as an error rather than just crashing
