I have been replaying the game and I think I accidentally skipped the quest name: "Stolen Tools" (page 66 of the walkthrough). Markus was there when I went to town with my daughter but I thought that I would talk to him after completing the current mission so after going back to the tower of dread and leaving the daughter there I went back to town and now Marcus is not offering the quest. I just wanted to know if any later quests depend upon this quest. Is my save effed up now? I have been playing the vanilla game without any mods. I have been 6+ hours in.
