I did that. The two ways are still separate (they do not highlight at  
the same time when one is selected, as I expect they should). Will  
they "become one" at some future time when the server figures it out?

Also, the roundabout I added at the end has a pulsating circle around  
it when I select it in edit mode; what's that?
