It might not be a bad idea to lock some character story elements behind the star rating of the Inn. I was confused when I was unlocked the library in Camilla's storyline LONG before I unlocked the ability to build special rooms. I thought the game might've been glitched for a while.
Also, there was a weird minor glitch where Tirria's "rubbing" scene was unlocked in my journal before I got to it in her storyline. Not sure how that happened. It was right after I talked to her in her room about being attractive.
