Hi Michael,

No worries at all — we’ve all made that mistake at some point. I’ve reverted your initial change.

When upgrading tags on a trail you've surveyed, it’s best to drag and drop the GPX traces directly on the map and split the path or road segments at the points where you turned back or changed direction. That way, you can safely apply tags only to the sections you've actually surveyed.

Also, iD has a feature to highlight changes, which helps visualize the edits you're making.

Best,
Julien
