Grouping of multi-part Skeletal Mesh LODs causes only one part to import

When setting up Skeletal Mesh LODs, groups within an LOD Group in Maya are now accepted on import as of 4.12. However, it only brings in one mesh from the group.

See attached image and fbx

1. Download the attached FBX
2. Import into UE4 with "Import Mesh LODs" enabled
3. Open the skeletal mesh in Persona

Result: There is no head. LODs work (there is a stretched vertex on each LOD level
Expected: All parts of the mesh are imported

Import failed of SM with Lods and multiple sub-objects
