There seems to be a compatibility issue between the remaster's apk and the chapter 12's apk, will look into it further. Haven't slept yet.

when I tried the book 2 it then said even if loaded the latest save that did not know me and needed to play book 1. Same if I just pressed start game. My phone is up to date and I'm using a Samsung phone if that helps u any. Liked the first book and can't wait to play the 2nd one. At least now know about the problem.
