When I first got into MS I got the History Books quest but when I defeated a boss later (can't remember which one) and tried to collect the book I wasn't able to "interact" with it so I checked my quests and realized the quest wasn't in my book anymore! So I went back to Jing Han He but he has nothing over his head so I can;t talk to him or get the quest again ... What do I do?
... What do I do?
