Thanks for the response!
Yeah, it looks very much to me like the version you grabbed was transitional or broken. For example, let's check out the precalculus branch. Here it is under 0.16.x:
Here it is under 0.17.x:
What's interesting is that if you go to the current KA site, it looks like the old version:
On the live KA site you can't see the whole tree expanded, but if you navigate around you'll see that it has far richer content similar to 0.16.x.
If you take a particular video -- say "Intro to arcsine" highlighted in the first playlist above, it is included in 0.17.x, but only appears under the "Class 12 (India)", the "in-in-grade-12-ncert" slug, not in any general area. This is true of lots of videos: they seem to have been pulled from the main playlists and put exclusively into India-specific curriculum playlists.
But if you go to the KA website or API now, you'll see that is no longer the case. That video is on the main playlist -- check out the path displayed here (this video is the first entry under "children"):
In fact, the "in-in-grade-12-ncert" slug, indeed the whole "Class # (India)" subtree is no longer accessible from the math tree:
It really looks like you somehow got a temporarily mixed up version. I am pretty sure if you rebuilt the English contentpack now you'd get a very different tree structure with most videos back in the main topics. And that makes a lot more sense for a general audience.
Is there any way to update this presently?
