I have uploaded a new build that fixes this error.

When clicking my results on completed quiz, I noticed it goes to my results page but this page is using quiz wrapper rather than lesson wrapper confusing the UI. Basically we start here, https://demo.xenbaker.com/lessons/lesson-with-quiz-support.5/quiz/
Then when quiz is completed, and view results, user gets lost in the quiz wrapper

Also, when using articles instead of videos, the table of contents do not bold font currently viewed page.

Also some errors for me.

Oops! We ran into some problems.

This add-on cannot be installed/upgraded because the following files are missing: js/ozzmodz/lessons/classroom.js, js/ozzmodz/lessons/classroom.min.js, js/ozzmodz/lessons/progressbar.min.js.

I had to deactivate all the add-ons on my site. Then, when I tried to reactivate them, I got an error message. Even though I downloaded and installed them again, I can't activate the add-on
