4.7.7
Place blueprint actor in level.
Copy or duplicate creates an instance not a copy.
is problematic for blueprints with construction scripts for random material change.
Dragging from content browser to viewport places a new blueprint actor that is not an instance and works correctly.
makes level building very slow.
ALT+Drag creates an instance as well.
