Does not occur in: 4.16.3

1. Create a new project > create a new Blueprint Class Actor > Name it "Parent"
2. Right-click on the Parent Blueprint and select "Create Child Blueprint Class" > Name it "Child"
3. Open up Child Blueprint > +Add Component StaticMesh > Compile
4. Right-click on the Child Blueprint and select "Create Child Blueprint Class" > Name it "Grandchild"
