Hi @aleksandr1592 -- thanks for finding this issue.

It seems from the database that the topic was there back when we built it.. inside "Differential Calculus", "AP Calculus BC" and "AP Calculus AB"... but all of the topics called "Continuity" where marked with available=0.

It seems that none of these topics container exercises nor videos in our database, so they were just empty topics back when we built the content pack.

It takes a lot of time and testing to release a new content pack, so I'm going to close this issue. The topic would show up, provided that we built another content pack and released it as a beta version. But frankly, at the moment, KA Lite is in a kind of legacy mode, and the timing is pretty bad for releasing things that might not work.

Not making any promises, but of course at some point, we could decide to build and release another content pack "without warranty" just to have the latest and greatest contents from KA.

but all of the topics called "Continuity" where marked with available=0.

They were marked that way because those videos weren't downloaded yet. I've investigated this issue and the results are still the same, they were just moved to a different topic tree.

See

@mrpau-eugene you're right that this should be investigated -- let's reopen!

Hi @aleksandr1592 - this will be fixed with the new content pack from the update here: learningequality/ka-lite-content-packs#78 (you will find a temporary link for the content pack there)

The content pack will be officially released for 0.18, but the new duplication of videos (same video appears in multiple topics) has caused issues with the download manager addressed in #5561 so we are not releasing it with 0.17.4.

If you are satisfied with the videos available from the previous content pack, you can download the full set with this torrent, containing all videos:

@aleksandr1592 to confirm that this issue has been solved, here is a screenshot for the Differential Calculus

[benjaoming]

Thanks for the confirmation @mrpau-eugene !

We can then proceed to closing this ticket once 0.18 is out :)

[aleksandr1592]

Thank you guys! I will test it when 0.18 is out.
