Orable Caron has nothing to do with Patric Cardone, and looking at the code, I'm not sure he is necessary for Thierry Bosquet - he can give you a hint but Thierry Bosquet is installed in the tavern right from the start.
Nothing was changed for any of the dialogs for Patric Cardone, Thierry Bosquet or Antoine Lebretton (St. Pierre tavern owner) in the post 28th July fixes. "PROGRAM\QUESTS\quests_side.c"
has been changed, but nothing to do with those sidequests - there have been additions to the "Apothecary" and "Sabine Matton" sidequests.
@lapuvida: do you have a savegame?
