Regression

(No) issue (does) occur in 4.11.2

Steps to Reproduce
  1. Open Editor (any project)
  2. RMB any static mesh>Create Destructible mesh
  3. Add Destructible Mesh to viewport
  4. In Details Pane, select Add Blueprint button>Name it DMBlueprint
  5. Create new blueprint in content browser of type (actor)
  6. Open New blueprint
  7. Add Spline, Child Actor, and Physics Handle components
  8. Set Child Actor to type (DMBlueprint)
  9. Create function in attached image.
  10. Compile
  11. Place copy of new blueprint into level
  12. Press PIE

Results

Editor crashes

Expected

DMBlueprint child actor component is grabbed by physics handle at specified location.
