Why not ask your question on the new OpenStreetMap Community Forum?

For the first time I tried editing the map, which went fine, until I tried to save it. Then I got a cryptic message:

"Version mismatch: Provided 1, server had: 2 of Way 250295839"

I have no idea what this means, how to resolve it, or how to save my changes. What does "Way 250295839" mean?

It means that someone edited the same way you tried to edit and saved the changes before you.

Way 250295839: http://www.openstreetmap.org/way/250295839 It seems like this 'someone else' is also you. Probably you had two browser windows open with editor and you did editing in both.

As I'm not familiar with iD, I do not know whether something can be salvaged from your unsaved work.

At the time of writing I believe the only way to resolve the issue with iD is to undo back past the problem and then save.

The way to prevent it in future (not that it helps now, unfortunately) is to "save early, save often".

Thanks all. that makes sense. It is likely that I had different browsers open. It is working now and my changes have been reflected. I assume that some more-experienced editor, maybe some sort of administrator, solved the duplication issue. Thanks to whomever did that.

As @RM87 says, it's an editing conflict. Somebody already uploaded a newer version of an object(s) that you wanted to alter, also.
