ranked_in_list returns incorrect ranks if some members dont exist

[clevercricket]

Use CompetitionLeaderboard and i have a set of friends - some of whom may or may not be part of the Leaderboard. When i call ranked_in_list with the complete list of my friends, it returns incorrect ranks for some of the friends who are part of the Leaderboard.

@clevercricket In this case, I would include the option include_missing=False in the call to ranked_in_list. This seems like the only correct option in this scenario, but I need to think on it more.
