I just saved one sim from Grim after she collapsed from freezing. She was on the street in front of my sim's house and my sim convinced her to group up. It would take too long to walk back to my sim...
A townie called Bruce Parks tragically froze to death at... yes you guessed it.. the park!
I was frantically using MCCC to change everyone's outfits to their winter wear so there wasn't a massacre. Thankfully the sim who died was a random townie I didn't care about and his grave is displayed in the park now forevermore.
