As the same with early versions, it happened again that the game doesn't freeze but it doesn't respond to anything, what i could notice is that the letters on the right like the one to see the hints goes grey.
Does it happen after a specific event, changing locations, talking to a character?
Right now can't remember, i think it was after a scene when the game made moving the character available again and the second after after it happened.
And like i said, it happened in previous versions too.
