Code 500 when saving changeset

[HubMiner]

Starting yesterday, when I save, I get a message:

Save changeset
500
[Cancel]

If I retry (Cancel, Save), I get the same message.

The changeset is probably not saved.

Chrome console:

You got a conflict. There is no implemented way to deal with it in Osmose.

requests.exceptions.HTTPError: 409 Client Error: Conflict for url: https://www.openstreetmap.org/api/0.6/changeset/149224330/upload

Osmose should report about the conflict rather than generic error. Also see #380

Confirming the diagnosis: I am able to save changesets when making small changesets (reducing chances of a conflict).

what can be done once this happens? Does it result in loss of all edits made since last save?

Can you save part of changes?

Yes.

Can you save part of changes?

Yes. It can be done.

how can I save only part of edits that were made?

By excluding conflicted objects, and resend.

how can you remove changes already applied that make impossible to save edit?
