Thanks Bernard, I will take a look at that. Am using 'Go Map!!' and do find it leaves additional nodes sometimes.

Hello @ivanbranco, I think that must be a 'legacy node' from when the house was just a point. I will edit and remove that, thanks for noting

Thanks Bernard that's helpful. I don't think GoMap has a facility to spot/show duplicate nodes, so it's also useful to know about OSM Inspector (http://tools.geofabrik.de) to find these. Using GoMap on iPad with Pencil - works really well, and is fast - but that last tap should clearly be 'dragged in'. Thanks

Perhaps I'm looking at geometry where you already fixed the duplicates, or perhaps there is a delay in refreshing the view here but I can't find the duplicates in the editor I'm using (GoMap)

Hi Bernard, thanks for your note. Can you give me some more detail of what I'm doing wrong? I just checked one house - the house has a shared boundary with its garage so I'd snapped the nodes together - is that OK?
