ah, yes, that makes sense. I’ve re-added the line of it in https://www.openstreetmap.org/changeset/151309993, but marked it as disused and private. This should hopefully mean it doesn’t reappear on mazemap. Let me know if it looks incorrect or if you have more suggestions for improving it. :)

Mazemap does seem to have a problem with paths/roads which are (correctly) tagged as access=private. There’s a footpath in the woods near Infolab21 and Hazelrigg Lane which is marked as private but which shows up as if it were public in Mazemap. Assuming that path still exists and is mapped correctly, I’m not sure what can be done about the problem in mazemap for it. Hopefully it’s less impactful than a path around Bigforth Barn though!

I’ve e-mailed the mazemap company to ask about this issue, as it’s likely to affect many of their customers, and could be causing people to incorrectly delete valid data from OpenStreetMap in an effort to fix things on their mazemap instances.

Anyway, thanks again for your improvements to the map, and for the time you’ve taken to research and explain them, it’s appreciated!
