As visible on this page of the official broadcaster site, this episode is officially the 13th episode of the 1st season.

I will left the special episode in place for a few days till the end of the week-end so you have time to transfer the data (guest stars, for example) attached to it.

After reading the Content Bible, I now get what you mean, my bad.

I would argue that while Dropout may list its specials and bonus content as numbered episodes, an exception should be made to separate them into the specials, even if they are technically sometimes numbered. There are very clear episodes that are season finales, and I think anything beyond those should be specials, but also understand why we should follow the broadcaster listing.

I also now have questions about the Dimension 20 listing (https://www.themoviedb.org/tv/89180-dimension-20) and its specials and bonus content.

Edit: I have created a report for Dimension 20 questions: https://www.themoviedb.org/tv/89180-dimension-20/discuss/66e3d5dd9013fe872223e11e

We need to follow the listing of the broadcaster. This is the primary rule.

For other shows than this one, please file a content report on the corresponding series pages.

It has now been removed.
