Sims wearing automatically swimwear to go outside since last update 29th July
Since the Last Update 29th July my sims constantly want to go outside home and automatically wear swimwear to go... This is pretty annoying and not logic being in Winter Season with Very Cold Temperature.
I think that i fixed it by myself : my home was build up on the water and each time all of my sims went inside this home or outside, they was wearing swimwear thinking they will go to swim instead of just using stairs to go up or down...
