No, before Kupper even appeared, I had already placed two candles right next to her spawn point. The candles didn’t go out during the ghost hunt. I remember that in the previous version, candles would go out during a hunt.The conditions were just right for placing incense in the ghost room at that time.At that time, I hadn't used incense in the ghost room yet. I thought it might have been a bug, so I quit the game.
