Nope only 3 hearts. well i guess play that again one day

here save with persistent.
Okay, you're gonna laugh, but you found another bug not related with the issue we had here in the first place.
The thing is that you did see all the four scenes with Rachel. You surely remember the scene with her in the park and then moving to her apartment, which is the fourth scene. The bug you found consists in the fourth heart being in the same place than the third one, overwriting it, but your persistent indicates me that you did see all her scenes.
So, conclusion: the bug about the fourth heart in the wrong position is solved and will be in an eventual v1.1 and the bug about the task not disappearing is not a bug anymore since it won't happen for anyone who plays the game starting in recent versions.
That being said, thank you for your help!
