Hello, the error message is intended because an edge that references non-existent nodes could lead to faulty simulation behavior. In earlier version of SUMO, the node information was not used as the network is completely defined by edges lanes and connections and thus the check was omitted. However, in the current version, pedestrian models as well as junction-behavior models make use of the topology information encoded in the node/edge graph. The error message would also help uncovering invalid netconvert behavior because networks of that kind should never be generated. If the problematic network was generated by a recent version of netconvert, please let me know. If the network was generated by a custom process of yours, please read http://sumo.dlr.de/wiki/FAQ#I_made_changes_to_the_.net.xml-file_but_it_did_not_work_as_expected._Why.3F
