My vampire sim doesn't know he cant go outside in the sunlight

Slightly bothersome issue indeed, I have a Master vampire with full lore skill and no sun resistance because she is meant to be more nocturnal but she just stand there burning in the sun when she returns from work! I've had a couple of townies die from sunlight as they tried to socialise and play chess with some normal sims.

I hope they'll start fixing this. It's not a bug but it is slightly frustrating and not to mention unrealistic, surely they would go inside.
