Add playing in mud puddles to the list...
My sims were obsessed with playing in mud puddles during a thunderstorm yesterday when I played. I had to lock them in the house for their own safety.
Ever since the last patch my sims are obsessing over specific things, often starting activities and being immediately distracted by something else.
It's actually making them really bad at taking care of themselves and it's driving me a little crazy at the moment. I really feel like the autonomy has gained some issues recently and I hope it will be fixed.
