After adding a class based on "Hierarchical Instanced Static Mesh Component", any attempt to hot reload, from Visual Studio or within the editor, causes the editor to crash.
Regression:
No - crash also occurs in 4.14.3 binary (CL 3249277)
UPROPERTY(EditAnywhere, BlueprintReadWrite) int32 TestProperty2;
Result:
Editor attempts to hot reload and then crashes
Expected:
Code is compiled / hot reload completes
