validator: badly fixes single node segments in way
|Reported by:||anonymous||Owned by:||anonymous|
I don't know whether this is the right place to submit validator bugs, but I'll try anyway.
If a single node segment is part of a way the validator deletes the single node segment, but it doesn't remove it from the way. If you upload your changes they will be rejected with a 412 "precondition failed" error. As there is no undo after you started uploading your changes, parts of your changes are lost.
See attached testcase.
