I had a broken link draw my attention to the below situation.

https://www.themoviedb.org/tv/292959-attack-on-london-hunting-the-7-7-bombers comes back with "Oops! We can't find the page you're looking for" I know that this was in the database before... I copied the link at some point earlier and saved it. So I tested going to https://www.themoviedb.org/tv/292959 and it redirects to the whole URL which tells me that it's still in the DB, just the page is shut off.

So I searched TMDB and found that there is a different ID for this show: https://www.themoviedb.org/tv/262277-7-7-hunting-the-london-bombers I'd guess that that entry predates the other that is broken due to the ID sequence.

My request would be that when duplicates are deleted, the redirect takes you to the copy being kept so that existing links are not broken.

Thanks
