Re: Stairs open to sky despite closed room and roof above it

I got a friend to test it out and his game does the same thing. If you have seasons, it will happen in every build that no matter what, your Sims, on cold days, will freeze to death inside without a thermostat to change the temperature. the stair glitch is something that is only the camera angle using the Sims 3 camera since the Sims 4 camera doesn't pan that way. 

so if you have Sims 4 seasons, this will be the reason. just add a thermostat to each build and you're good. Hope that helps!
