When I try to upload my changes a message appears: “Version mismatch: Provided 3, server had: 5 of Way”
I guess this is when someone else changed the same way as I did between download and upload. How do I handle that now? How can I still upload the other changes I’ve done or resolve the conflict by updating the way to the latest version in JOSM?
I had to add an additional tag to the way, then resolve conflict showed the new tag and I could resolve. Then the upload worked. But afterwards I had to revert the way in Potlach to the old version because josm did not update to the new version correctly.
