[OSM-talk] Crazy ways after editing

[David Muir Sharnoff]

The area of Oakland, California I've been editing
(with Potlatch) suddenly changed in a very bad way.

There are a whole bunch of ways (at least 50,
perhaps a lot more) that have had one or more
of their points move several miles south-east.

A major street, Park Ave, seems to have
disappeared entirely.   Or, at least, I can't find
it any more.

Edit at this location to see:
http://www.openstreetmap.org/?lat=37.81886&lon=-122.21229&zoom=16&layers=B0FT

Some example ways that are messed up:
6403309, Saint James Dr.
6380125, Somerset Rd
6365079, Pershing Dr
6391271, Indian Rd
6381464, Hampton Rd
6374990, Excelsior Ave
6359191, E 33rd St
6390297, Everett Ave

Does anyone have any idea what happened
or how to fix it?

Thanks,
-Dave
