With the update to the playlist yesterday I was curious, so I checked archive.org's saved page from Oct. 12, at which point it had 24 videos and 1 unavailable, hidden video. Since Oct. 12, 7 videos have been added to the playlist to bring it up to 31 videos with 1 being an unavailable, hidden video. Not sure if that hidden video means anything besides there possibly having been a private video left in there for a while now. Not sure what about the playlist would've been updated yesterday, though... Anyone know if the "Brilliant Diamond and Shining Pearl are available NOW!" video was already in there?
Here's a link to the archive if you're curious, didn't want to post the image because I think it's forced to light mode and it's a bit blinding after using dark mode for everything.
