Re: [V] [SE] Vampire freezing to death
My Servo nearly froze to death when visiting the Onsen Bathhouse lot in Snowy Escape. Game version 1.75.125.1030. I was about to file a bug report, then found this thread.
As per the OP, this looks like it's a problem with the Onsen Bathouse lot specifically, so it's not just vampires or servos it's any Sim that's supposed to be immune to temperature extremes.
