Crash saving a destructible mesh after creating it from static mesh

Crash occurs when saving a destructible mesh after creating it from a static mesh.

1. Open QAGame in editor.
2. Right-click any static mesh (I used Barrel_02) and select Create Destructible Mesh.
3. In the Destructible Mesh editor, click Save.

RESULT:

Crash.
