And I do have one last bit of evidence to proove that Knuckles is still guardian of the Master Emerald in modern Sonic games. Knuckles profile clearly states he is still guardian of the Master Emerald, regardless if he's invited to adventures, birthday parties or not.

If Sonic Runners count as canon, then Sonic Generations is the third most recent main series Sonic game and thus take into account the modern Sonic games from Dreamcast and Modern era as well as Lost World and Runners.
