Hmm, it seems it might have just been a glitch, as I literally just went to the very same Sim (who does not have both as I previously thought, just Iceproof) that had frozen to death last time I played her (she was saved by her familiar) and just had her swimming laps in a swimming pool and I even went all out and put her in her warm weather outfit prior just to try to maximize her chances of death by freezing, she was happy and having fun, not freezing.
So seems it IS working... sort of? Like its possible there is still a glitch somewhere but seems to be working now.
EDIT:
Okay, spoke too soon... here she is frozen, as you can see she has the buff that she should love the cold but she ALSO has the negative buff and that just killed her (again, her familiar will be able to save her, but still.)
EDIT: Okay so a bit more testing, it seems you DO need to still wear your cold weather outfit. As you can see there she's wearing her swimsuit and then after she warmed up after that brush with death, I saved and then took her back out... she was fine until she put on her bikini the stated to freeze again, swapped her back to her cold weather and she immediately dropped the debuff.
I guess it doesn't actually say you can't freeze to death, just that you enjoy the cold. So maybe it's not a bug, just a bad name that implies it does more than it does?
Have you ever noticed your sim with the Heatproof / Iceproof trait be negatively affected by the weather BEFORE any sim in the household without those traits? Because that's what tends to happen in households for me; especially indoors. They also still have the blizzard walk.
