In the grid of videos below the video player, I only see:
Parts 13 & 14
Missing Parts 09-12 in between.
I don't know if there's an episodes list in the backend, or how it works. I just finished watching Part 10, and the autoplay "Next up" took me to Part 13. That kinda suggests to me it's more a problem with which episodes are stored in a database or something. Rather than the Grid/Carousel itself. (I don't know if that makes sense.)
Changing the various sort/filter options doesn't reveal the missing episodes.
For now, I'm having to select new episodes via the Rogue game page's videos section, or the Videos -> Premium page. Both of those pages show the missing episodes.
