text: do you remember where the first one was?
  
  the shorter overlap stretch is gone, so the amazon turn restriction must be broken.
  
  ugly, the sort of inconsistencies this caused.  there were a handful of amazon additions attached only to the way i deleted; similarly there were around the same number of additions only attached to the original road way and that did not get attached to the new way.
  
  i was  aware of the former, but not the latter.  maybe the joined added way is more random than i thought.
  
  anyway, everything is attached now except one of the two simultaneously-edited ways you pointed out, due to the version conflict (p2 would abort and leave the earlier edit intact, while it looks like iD was able to allow the later amazon save to break the earlier one).
  
  anyway, i'll turn the turn restriction over to you as there are too many basics i need to learn.  i wonder if iD will break things like this again...
