Sims 4 Seasons: Adding thermostat to every building?

@Nushnushganay I don't think thermostats are broken, they just didn't program them to auto change. You need to click on it yourself to change the temperature.

@SimAlexandria I think @LindsaySeddon1 probably just meant in unplayed sims houses. There is no need to add thermostats into unplayed sims houses because they are never loaded unless you go visit them, therefore the sims inside the houses won't die in there. It is, of course, possible for other sims to die while they are outside in the cold.
