Well this quest bug is specific to Cecilia or Cece, it happens when I go to town at night and call for her, and she asks me what I want, at that moment the dialogue doesn't advance anymore and this is in version 0.4.1 of Android.
This happen in android and mac version. I was playing the android in blustacks because my cellphone usually cracks with this. In bluestacks works at 100%. Doesnt have any problem. Untill the moment after finish the Rika second history. Just after the werewolf night in the bar. If you try to go to the town on night. You will found Cecilia. And she will ask you what do yo want. After that the game cant continue. Doesnt crack. Is just like a dead end. A soft block. You couldnt choice nothing to continue and the chat box never changes.
