if your getting chased by a hyena at the one point and get stopped by the kitsune asking for their bracelet,it freezes and locks the game.
also if you go through the host club and the secret entrance,im not sure if its a bug,but it kind of acts like your in slut mode?,i had to brute force the save to beat the three guards before the boss normally,it wanted me to do the service stuff,to be clear i only lost once to do the host club route
