More hardening with digitla ocean

some ref handling was a bit strange, now it's rendering correctly. I have a feeling we will be back to the diff engine at some point soon, it's picking up some strange changes that are so deep in the model, I can't determine what is what, so we will wait for another set of triggers to appear.
