Have played further into the game, and still experience glitches like people not being where they're supposed to be like I described in my previous post, however I think it may have to do with the change in how time advances. For example, when you get to the part of Amy's story where you go to her house for dinner to confront her husband, it took several attempts to get it to trigger. What I ended up having to do was just spend the entire day standing at her house and skipping time until the event triggers and she opens the door. It took 3 fridays of me doing that before it finally triggered, but it did trigger eventually.
