TVDB link missing

Today it looks the the TVDB link button is missing. What happened? It was vary useful to have links to the main sites there. Is this a bug from the change with the comparison page?


It’s back for shows that aren’t migrated to TMDB yet.

Is it only going available to be for those few shows? Why remove it from the rest of the shows, TVDB has different and or more information than TMDB.
