Visitors to my Sim's lot keep leaving fairly quickly with thought bubbles over their heads that show what appears to be a pink icon for...hot chocolate? Or coffee? I'm not entirely sure. I have NightLife, Seasons, Bon Voyage, University, FreeTime and Celebration Stuff. I have seasons set to constant autumn, and it doesn't seem to be all that cold out. Even when they're indoors, they suddenly just...leave. No matter the time of day. I've used the InSimenator to control the outside temperature as well as everyone's individual temperatures, but they still leave far too quickly for my tastes. This is a fairly recent change of events. Does anyone know what this steaming-mug icon represents?

Did you patch each EP and the one SP if you have it as you installed each one including the base game?

The icon represents that they are feeling cold, but the circumstances don't sound normal.

How do I do that?
