FF13-2 is a butt about figuring out where to go. I played one day, stopped before entering a rift... saved... quit. Came back the next day, and LUCKILY I had just figured out where I had left off (Anytime you quit, you go back to a screen that lets you pick which time period you want to go to... so you can go off and quest outside the main storyline to level up or whatever.)
