So i found 2 of the letters in chapter 3. The one in the bedroom. and the one on the table. Where is the last one?
Also idk but Touched could be glitched as i know quiet knoll glitched on me as i played through the game twice without tapping and it wouldn't pop but the next time i went through the game knocking all over the place it popped for me.
Edit: NVM i found it.
but didn't unlock the touched trophy either. There twitter would only tell me that i have to probably replay the game and collect some touchstones but its not working. I know i've at least found one thing that i had to interact with that wasn't highlighted which was a statue.
