I agree. I don't think that the 'specials' series should be locked. It being listed as 'series 0' stops it appearing on sites like Serialzd and stops those of us who like to log these things from being able to do so! I think the specials should be attached to the end of the series they followed - i.e. the three that have aired this year should be attached to Flux as Jodie's last series. Justice for the Serialzd users!!

This episode is correctly listed in the Specials season.

As visible on the official BBC page, these episodes aren't part of season 13.
