@p.gomes, I noticed the same thing. I also noticed my city (Keller) had an OSM update on 10/20/20. So I think the OSM update brought back the 0-node streets. @JamesChevalier had posted that he ran a global delete on 0-node streets, with, I presume, the knowledge that the next update will pick them back up. Looks like that happed, but they still have 0 nodes.
