I think you could've managed to be slightly more vague, here. The specific date-times mean that it might be possible for me to figure out what you are talking about if I wanted to do a lot of work and also presumed that you didn't just make up many of those included details.

But I'm lazy.

Care to actually mention one or a few of the node_ids that you believe have been re-used and maybe even what you saw that led you to believe that re-use had happened?
