Not all of them; I know I was at Bell's office with the Bells looking at Mark G's phone right before it happened. Other than that I saw the small park and Mark G's apartment that chapter, but I don't think that was all of them.
Dang, okay! Investigating the phone should have opened up a new link on the world map. I just uploaded a new version of the game with a fallback option on the world map if that logic breaks. That should at least get your save file unblocked while I investigate further. Sorry about that!
