There was a post 12 hours ago to the talk list about the exact same thing...

Richard the author of potlatch explained the issue in his reply to that post
11 hours ago as being a partial written save due to server load or network
problems or some other weird issue, the result being that ways can contain
nodes that are deleted...

As Richard described in his mail, the best tool to fix this is potlatch
itself, reopen the area in Potlatch, modify the way that has a problem, e.g.
by moving a node then moving it back, then unselect it and the data will be
resaved with any missing nodes reinstated...
