Yes!! that's the one main problem!! Even if I did boot up again and again, I still had start from very beginning again after i try save Neil chp14 and getting tired from start all over (TT~TT)
At the moment, I can't fix it for you (version 1.5 will not have this issue), however since it seems to happen after you finish a chapter and save, my suggestion would be to only save in the main menu settings instead. So at the end of a chapter, when it asks you to save/load, click cancel. Then, when you're in the main menu, open the settings and save there instead. That should work.
