Missing Korean lesson?

In the LingQ 101 - Getting Started lessons for Korean, there are supposed to be 10 lessons, but Lesson 1 is missing. I thought that might be a temporary situation due to some technical work being done, but it has been missing for weeks. I’m new to LingQ, so if I’m misunderstanding something, let me know, but it looks to me like a lesson has been accidentally removed.

@JDHallKY - Thanks for the heads up! Not quite sure what happened here, but I’ve now added this lesson back.
