I think it is because both networks are oneway subnetworks not
found by the normal subnetwork procedure (but by the
oneway-subnetwork procedure) and you defined the oneway minimum
size to 20<br>

<div>Hi John,<br>
<br>
it should not be related to calling these
method twice. It is just one time where
you calculate the subnetworks independent
of any FlagEncoder or direction via
findSubnetworks and the second pass is
FlagEncoder- and access-dependent via
removeDeadEndUnvisitedNetworks.<br>

There are two
types of
subnetworks and
the smaller ones
seems to be
'one-way
subnetworks'
which means they
are eg. only
reachable as
destination or
start. But if
you would start
from a
destination-only
subnetwork
you'll get 'not
found' for all
points outside
of this network.<br>
