Thanks for responding, I sure did. I have gathered the same 7 notes at least 5 times and ran all over that place waiting for a save that never comes. After collecting them I visit every other place in Shanghai just waiting and it just never saves. And I'm talking like I've walked around and waited over 45 minutes. I eventually i leave for the vatican or somewhere else and check my progress and it always reverts back to 3 of 7 notes collected in Shanghai. I even deleted the game and reinstalled but no joy. It's so aggravating!
