Just to be clear, I am not part of the development team. I'm just a fan of the game who has experience with coding and game development. I've never seen the bug you're talking about with the transformation, nor have I seen the hair bug. You'll have to be more specific about the dialogue hang. Also, it helps if you include the version of the game you are using (ie., ver4.1 windows or ver4.1Mac). The team will probably not be supporting versions prior to 4.1, and different operating systems could handle the code differently.
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.
