	if r.con_route is None:
	el.add_error(r.system.systemname + ".csv: root " + r.root + " not matched by any connected route root.")
	# check for mismatched route endpoints within connected routes
	q = r.con_route.roots[r.rootOrder-1]

results in

ERROR: usame.csv: root me.me021 not matched by any connected route root.
Traceback (most recent call last):
 File "./siteupdate.py", line 2942, in <module>
 q = r.con_route.roots[r.rootOrder-1]
AttributeError: 'NoneType' object has no attribute 'roots'

A simple continue should fix this.

C++ version does not crash, because rootOrder is initialized to -1.
Python does crash. Fixing.
