Complete all challenges for any of the Clubs. (27)

This trophy is likely to be time-consuming. There are 4 Clubs in the game: Boston Brawlers, Frontiersmen, Hunting Soceity and the Thieves. You must finish all levels of challenges and complete the side-missions associated with one particular Club. To check which challenges are available and those you have completed, access the DNA Progress Tracker and look them up under the individual Club DNA strand. All Clubs must be completed 100% for the "Completionist" trophy anyway, so you will get this trophy on the way to achieving that.

Note - There are no side-missions for the Thieves Club.

Note - It seems that if you talk to Washington before unlocking the second tier of Frontiersmen challenges, then the game will bug on you. However, there is a fix, which is to reload Sequence 9 Memory 1 ("Missing Supplies") and talk to Washington twice there.

Thanks to Zanish09 for bringing this bug to our attention, and to jamesdevil for providing the fix.
