When I enable the button under publish says save rather than "save draft". If I click the save button the post simply disappears. I have found out that the post does get saved to the db but as an auto-draft, so you can't get at it in the admin to edit it or change status etc.
Right below the button show "Status: Draft", but the button doesn't reflect that. If I edit the status and select draft and hit OK, the button does change to "Save Draft", and then it will save just fine.
If someone forgets to do this step they can loose a lot of work. Shouldn't that button default to "Save Draft"?
If I disable the custom statuses module in edit flow, the button defaults to "Save Draft" and works as expected.
