Online version 2.1.3 - I cannot "Publish to file" from a specific story

I am able to publish to file on other stories I have created still but a particular story does nothing when I click "Publish to file". It does nothing from choosing that option in the story itself, nor from the setting option on the main page where it says "5 stories": http://twinery.org/2/#!/stories

At the moment my story is a work in progress with some disconnected elements. Would this stop me from being able to publish it as a story? If so, does anyone know of a way for me to be able to share the story in its current state with a collaborator?

Thanks in advance!
