GeoMason bug? ClassCastException for GeomPlanarGraphEdge

Hi,

I'm using GeoMason to make a city simulation (agents walking along roads
between houses) but might have come across a bug. I want to get the road
network (a sim.&#8203;field.&#8203;network.Network object) from the field (a sim.&#8203;util.&#8203;
geo.&#8203;GeomPlanarGraph object) to find out if the graph is connected or not.

But the call to 'network.getNetwork()' causes the ClassCastException below.
You can re-create this bug in CampusWorld but putting 
'network.getNetwork();' anywhere (e.g. I currently have it as the first
thing to be done after the super.start() call in the CampusWorld.start()
method). See the output from CapusWorld below.

Any ideas?

Thanks,
Nick
