Just a 'me too' here. On release day an NPC jogger froze (Marcus Flex) outside the gym and everyone ran out to witness his death and reaping. Since everyone had been working out in exercise gear a chain reaction kicked off freezing ten sims before I quit out. I'd post a pic but I get the 'must be around longer to post this' crap.
LittleMsSam has a small mod to fix this problem that she's working on in her Discord support channel in the #feedback channel. Just search for "no freezing to death mod" in the discussion there for a link. I can't seem to post any links but you should be able to find LittleMSSam, she's a prominent modder.
