Seasons – Can Sims Even Get Sunburns?

How do you get a Sim sunburned in the Sims 3 Seasons?? I’m thinking it’s a bug in the game because my Sims take a nap outside in their bathing suit in 90 degree weather and only get a sun tan. I’m trying to complete the ‘Fair Skinned’ badge of getting a sunburn and haven’t been able to. Just wondering if anyone has been able to yet.
