The problem here seems to be in the EditShipmentInformation function. If I bypass that and only insert a Billing address I get to the next stage. Unfortunately, at that point it falls over as it can't find the Shiping address
Value cannot be null. Parameter name: shippingAddress
"not-null property references a null or transient value"
Getting the error
Att the address/shipping stage.
I am using a custom shipping mehtod, but it works fine on my existing test version of this site.
I should add: This code works in one instance. If I duplicate it and run in parrallel on the same database, I also get this error

Further battering about with this defintitely highlights this guy:
As the break point. The address gets created but it falls over (creating the shipment?)
Bult the site from a clean install and the error went away
is working on a reply...
