Werewolves in human-form are immune to temperature

I love the werewolves, but there was always one thing that I found a bit annoying.

In their werewolf form they are immune to any temperature, too cold, too hot, it doesn't matter. But when they switch back to their Sim form, that was it for the immunity.

Somehow that bothered me all the time. Maybe it's just because of the books I've read, because in them the werewolf was always referred to as the counterpart to the vampire - their body temperature is higher than that of an ordinary human and cold and hot weather doesn't really bother them.

And that's exactly why I made their Sim form immune to temperatures.

Just so I can have peace of mind.
