When in a category overview ('Home > Courses > CATEGORY') if there are more than 10 courses listed, they auto-collapse and any video content within does not play. The video content is embedded via <a href="CONTENT">TEXT</a> code in the text box of the course overview.
To reproduce this, add 10 courses to a category. When viewing the category overview page the courses will all be expanded. If you then add another course to the category (a total of 11), and view the category overview page, the courses will be collapsed and when a course is expanded any videos embedded via the 'href' method within it will not play.
