Students cannot save their work with latest version.

Some of our courses have many modules and questions within pages, and in the latest version of the plugin, if they choose to take a break and the window closes their responses are not saved and they don't seem to have an option to do it manually.

In a previous version, there was a save button at the bottom of the page, so we had included reminders to save in each unit after they had answered some of the questions. This 'save' option is no longer visible.
