This often happens to me in Potlatch. Here's my usual use case. An intersection 
of two streets needs to be converted to a roundabout.

1. Split each street at the intersection.
2. For each of the 4 ways, select the way and the intersection, hit backspace 
and reposition the end of the way where it should intersect the roundabout, 
forming a diamond.
3. Create a new way for the roundabout, incorporating each of the 4 ends of the 
ways.
4. Tag the roundabout appropriately (e.g. junction=roundabout, 
highway=residential, source=nearmap, maxspeed=50)
5. Save and quit Potlatch.

I then come back some time later and find that there is an empty node in the 
place where the intersection originally was.
