[Bug]: It seem we cannot download those preview lectures in a course.

What happened?

I was downloading a course in my personal plan. After download was done, I found the preview lectures were missing. And I've checked the logs, which showed that INFO: > Lecture '001 Introduction' is missing media links. So it will not download the lectures without the media links. I was using the lastest commit. And I reverted back to commit 745ea11, it worked. So I believe there is a bug in the lastest commit.

Expected Result

The preview lectures should be downloaded as well in order for the intact

Branch
