Nothing so mechanical, but I guess you could call that 'mini milestones' .
IF we didn't sort out some of the "Who the hell is stealing all of the beer making supplies from the local farmers?" we would not then figure out where to confront the mini boss who was doing it (using his thugs to do so .... We tried to talk him out of it, which was where most of session three went, but we also figured out during that failed attempt that he's not the Big Boss behind it all ... and so on.
