Fairy sim death by freezing

My fairy Sim one kept changing into his swimsuit to fish in the pond off the stream in innisgreen and then he started freezing so I tried to change into cold weather outfit but for whatever reason he wouldn’t he’d just stand there making different faces so I made him go home and he got there then it said he was freezing to death the interaction was there but for whatever reason he just wouldn’t die my game was in three speed because he was a bit of a walk away it said he was dying for four whole sim hours before I decided to quit without saving
