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...
I lost a child sim a couple of days ago while he was on a 'play date'. While he was there, before he could step inside the house, a fire broke out. It was winter, and he froze to death waiting for the fire to be put out. This is ridiculous.
