Hi aselvadeasfalto, thanks for your response. 

For some reason my revert only deleted about 8% of the orphan nodes, so I'll try to get someone with more experience to look into the issue 

I did my revert using the osm-revert site (https://revert.monicz.dev/). It's very user friendly, I prefer it over the JOSM reverter. It usually works just fine lol.
