[AA] [S] Sims dying from overheating/freezing in camp with correct clothing

After installing Adventures Awaits, my adult Sim died from overheating. She was at the Gibby-Gibby Children's Camp. She had a cold and was drinking green tea. I saw the red "Overheated from Abnormal Heat" moodlet. But it was autumn and cool with partly cloudy weather. I changed my Sim into summer clothes. She walked outside from the cafeteria and died. The family tree lists the cause of death as heat.
