Fear of dark bug

The fear of the dark cannot be conquered. The bubble says to conquer this fear become confident outside at night. Going outside at night while confident doesn't solve it, becoming confident while outside at night doesn't solve it, drinking a confidence potion outside at night doesn't solve it. And while drinking a fear-be-gone will erase the fear of the dark bubble, the sim remains afraid, gaining the scared moodlet anytime they are in the dark.
