i am having the same problem no matter how many times i reload and replay it , also when i save it shows that the sister is with them , or walking around there are 3 characters instead of just the two .
At this stage its just too frustrating to try and play this game along with not having a clue of where to go and constantly having to check forum to try and progress in the game ,
i am a little disappointing as i do think it has the makings of an enjoyable game , so i do wish the Dev the best of luck with it and for his effort ,
i will keep an eye on future updates in the hope that it can be made to run more smoothly ,but at this point for me its just unplayable without having to resort to dowloading other peoples saves an missing content and constantly having to restart from freezing issues
