Source please?

I think @darkburner's issue here can be explained by the difference between the English original (!) and the German broadcast. The German one differs a lot in later seasons for reasons I don't know. And I don't actually care about, because TMDb is only interested in the original airing. The primary source is this one - it contains all episodes:

http://www.history.com/shows/ancient-aliens

(Just for reference: Here's the German source and an overview of the differences -> the overview contains a few bad mistakes, though ...)

I just went through all episodes of the show and checked -> apart from a few mistakes, everything is fixed here on TMDb

However, there's one thing I can't figure out. The primary source includes 8 episodes in season 9 (S9E13 to S9E20) with recurring episode titles, starting here:

http://www.history.com/shows/ancient-aliens/season-9/episode-13

I'm not sure why, but the German source calls this a spin-off under the different title "Ancient Aliens – Neue Erkenntnisse":

https://www.history.de/sendungen/ancient-aliens-neue-erkenntnisse/staffeln/staffel-1/episodenguide.html

And I can find websites in English which call those episodes "Ancient Aliens: The Ultimate Evidence", for examples:

http://www.radiotimes.com/tv-programme/e/dvqb2c/ancient-aliens-the-ultimate-evidence--s1-e1-beyond-nazca/

The writer of the first example is/was as confused as I am -> I have no idea where to put those 8 episodes here on TMDb?!?

The one thing that confuses me the most is some of the episodes names are identical to episodes which aired during the original season five. But you can also see them as part of the season 7 in the 2015 web archives.

Actually, all 8 titles are identical to episodes that were broadcast before:

S9E13 -> http://www.history.com/shows/ancient-aliens/season-9/episode-13 -> Beyond Nazca = S5E8 -> http://www.history.com/shows/ancient-aliens/season-5/episode-8

S9E15 -> http://www.history.com/shows/ancient-aliens/season-9/episode-15 -> The Tesla Experiment = S8E6 -> http://www.history.com/shows/ancient-aliens/season-8/episode-6
S9E16 -> http://www.history.com/shows/ancient-aliens/season-9/episode-16 -> Alien Power Plants = S5E3 -> http://www.history.com/shows/ancient-aliens/season-5/episode-3

I have no clue if those are the same episodes? I guess not, maybe they edited the original footage? I'm confused about this, too ...

I just read the review you linked to in which the guy explain which parts were cut/added to form the "new" episodes. I think we can probably just bend the rules a little and added them as specials e.g. The Ultimate Evidence: Beyond Nazca. What do you think?

Argh - I'm dumb! I started to read this review, and then I stopped when I thought: "Okay, now it's getting into the content and I don't want to know about any of it." Which means I actually missed all the cutting/editing and what the reviewer wrote about it!

Yes, I agree. Just did, starting here:

I think this issue is solved now.
