Basically, if the server goes a bit boggly (under high load), it's  
possible for an operation to abort halfway through - because we don't  
have transactions - and so a way gets to contain deleted nodes.  
Potlatch and (from memory) the API history call will show the deleted  
nodes, the API map call won't. lists.osm.org appears to be down as I  
write this but it's been discussed several times in the past.

The easy fix is to edit the way with Potlatch, make some sort of  
change (maybe drag a point away, then back again), then deselect to  
force an upload.
