MongoError: topology was destroyed #9

The following error appears to have killed the flow library. A quick restart and it was up and running again.

Recording it here as there's probably some error handling missing...

Happened again today.

Based on some research, have set saveUninitialized: false of the express session - will see how that holds up.
