I have gotten to a point in the story where I have been warned that if I proceed, I will not be able to return to the north. This will lock me out of the lost lake area of the game. Is this permanent or just for a portion of the story?
I want to be able to get the platinum trophy and I have not completed all of the things needed in this area. Can I come back and clean up at the end of the game or do I need to get this stuff done now? I've made a game save to be safe so I can go back to this point in the future to get trophies.
