What Happened to the Champion Insights on Soundcloud?

So, for those of you who have listened or continued to listen to the Official League of Legends Podcast on Soundcloud even after they long since stopped doing it, you might've noticed that some of the episodes (is that the proper term for it?) have gone missing. Before, there were episodes (?) for champions like Aurelion Sol, Taliyah, and Jhin - about around the start of 2016 all the way up to around the end of 2017 - but now these have mysteriously disappeared!

And if that wasn't strange enough, only the episodes (?) about Camille, Warwick, and the "Worlds 2017 Top 20 Players" are left! What happened to the other episodes!? Will they ever come back? Please, if anyone knows why this happened and if anything is being done to fix, let me know! I've listened to them over and over again, but I never get tired of them! I just want them back!

If you're reading this and don't have an answer, could you at least upvote this post so it has a better chance of getting noticed and potentially solved? Thank you!
