Something that has been bugging me with Seasons. I'm not sure if this also happens in Fall too, but my god.. my Sim will be sitting on the couch, check the weather, and notice the extended forecast...
Monday: High 66, Low 42
Tuesday: High 73, Low 57
Wednesday: High 74, Low 58
Thursday: High 36, Low 27
Friday: High 67, Low 45
Etc..etc...
Seriously, this isn't normal. If those temps were real life, they would make you sick like heck. You can't jump from a low of 27 to a high of 67 without a significant cold front. And it showed it was sunny those two days, Thursday into Friday.
