Does look like some of the now-vacant units didn't have addresses initially listed. But I can look into individual nodes deleted in the U.S. and U.K. so far to see if it's possible to place some back in as vacant units with an address.

That is if there is any way to reverse my own edits so I change things.

1. I was doing the edits manually. They were not automated.
2. If you want me to keep the marks of the units with their addresses, I can try to see what I can do.
