Course Presentation

I'd like to do the following, but not sure if it is possible:

I have a course presentation with a couple of slides.

One slide contains an interactive video. At a certain point in this video the student should be allowed to go to a certain slide of the "parent" course presentation. So similar to "go to slide" of a course presentation object, but triggered from it's child.

Would this be possible? 

Not sure if this is considered a bug, but I found that if you use a Question set in Course presentation, the title of the Question set won't be shown in the summary. Instead the first question in the Question set will be shown.

Like in the example on H5P.org: https://h5p.org/presentation#example=612

The first question on slide 2 will be shown in the final summary page, and not the title of the whole Question set.

So we've had a report from one of our users that a course presentation they've created has become corrupted. As soon as they enter into editing mode, they're unable to navigate past the first slide. Likewise, when viewing the presentation, they're only able to see the first 6 (of 24) slides.

This occurred in our Wordpress instance of H5P, but we've also tested it in the Moodle plugin and on H5P.org with the same results.

Any help would be greatly appreciated.
