Had a look through the topics but could not locate any that addressed this question: if these objectives are added to the staging area in quest stage 1 (1st Hobbit quest) before any trolls appear, does this mean they can never be claimed? That they are simply placed in the staging area unguarded and thus are never attached to a troll? Which means ultimately heroes cannot have Sacks removed by Bilbo (hence, at all)?
Maybe I am missing something but if not it seems overly harsh that you can practically lose the game at the turn of the first card.
