Right now, because of the way background and foreground objects are handled differently in the editor, there's a limitation:
When duplicating objects, only either background objects or foreground objects may be selected. If both types are found in the selection, the game refuses to duplicate.
I think this should be a "might fix later" kind of issue. It requires restructuring quite a bit of code - which I'd like to do anyways, some day. Basically: Background objects and foreground objects should be unified in the editor as much as possible, which they aren't atm. This is a direct result of the fact that they're handled to differently when drawn - bg objects are batches, foreground objects are visualizers.
