An alleged update called Reveries that allows them subconscious actions. Sort of like how when you remember something but you're not really thinking about it, but you twirl your hair around your finger. Or you tap your thumbs on your desk. Or bounce your foot. According to one of the makers, it was supposed to make them more realistic to the guests, but that turned out to be a lie. Someone else gave them the code as a way to access their previous memories, despite them being "wiped." It turned out it was actually to help the hosts gain sentience and create life.
