unique portal names are the culprit!

MIC --

You're right in that the portals are (I think) doubly-connected. I did 
notice, just now, that portal names are NOT globally unique in your files. 
I'm putting some stuff in my code now to work around this, but you should 
make sure portal names are unique next time you run data.

You gonna be around at all today?
