[OSM-talk] JOSM upload failure

[Stephen Hope]

I was uploading a big section of data when I had an connection failure
of some kind, and the upload eventually timed out. It had uploaded a
lot of nodes, but hadn't got as far as the ways yet.

Can I assume that if I just try and upload the same data again (I have
it saved) that it won't duplicate the nodes that uploaded last time?
Is there some rule that says you can't have two nodes in the same
place?
