Unless / until you turn up your logging detail or add some tracking
tools (see also 'debug_print') you can only be sure what took place with
those routers that do what was expected of them and leave footprints in
the logs. Or somewhere else recoverable/visible.
So the 'NOT offered' may or may not be correct, and may or may not be
for the reason you believe it to be such.
