Set Material for a DM in the Construction script will result in a crash

Setting a material in a BP construction script after setting a DM will result in a crash. This will render the BP inaccessible once the project reloads. Opening the BP will result in an instant crash.

[Link Removed]

1. Open UE4
2. Create a DM from a static mesh (no need to fracture or anything more)
3. Add this DM to a Blueprint
4. In the construction script use a Set Destructible Mesh node and a Set Material Node (no mesh or material assignment necessary, see attached image)
5. Hit the compile BP button

Results: Once the BP is compiled the editor will crash. Attempting to open the BP once the project restarts will immediately result in a crash. The BP is now unusable.

Expected: The Blueprint will compile and not crash
