I figured out what I did and how to reproduce it, so hopefully this can get fixed Or at least maybe you've been warned so you don't do this to your Lesson Schedules.
There are two variations on this. I'm listing them both in one post as they are very similar and possibly related.
Variant One
- Prerequisite: I can edit the Lesson Schedules. Be in a 2013 class schedule.
- Create a test class. Just type in the name and hit save. You don't need to select anything else.
- Click View Year for the new test class
- Select a date and edit the class for that date.
- Select a class type where you enter a URL for the lesson.
- Enter the topic and the URL.
- Save
- Verify that it displays properly and the URL works.
- Select Administration.
- Edit the test class
- Press Save (you don't even need to make any changes)
- Click "View Year" next to your test class.
- Observe that all dates where you have specified a custom URL entry have been completely obliterated and replaced by something like "New Lesson" or "Not Specified".
- Cry
- Prerequisite: I can edit the Lesson Schedules. Be in a 2013 class schedule.

- Click View Year for the new test class
- Select a date and edit the class for that date.

- Cry a little bit less than Variant One
