The only oddities I've noticed so far are the excessing bathing/showering and the excessing water-balloon pranking. I'm playing autumn but I thought water-balloons were supposed to be a summer thing. I also don't have the "Try On" option in community lot clothing racks and no "Outerwear" option but I'm going through my hacks right now to see which one could be the cause of that particular problem. Oh, and the autonomous changing into outerwear when it's not cold outside.
The excessive water balloon prank is annoying but I think it is a feature. The bathing/showering is due to heat (I think). Is their thermometer in the red? Mine were all red all the time and I finally traced it to the InTeenimaor. I removed that and everything is fine now as far as the bathing goes anyway. I've noticed in a dorm I'm playing a couple of the girls (non-playable dormies) keep fighting each other and the cafeteria worker, slapping, shoving and actually fighting constantly. I've never had that happen before.
I forgot I had inteenimator installed. I have removed mine and hope the next time I play it fixes my thermometer too. I am tired of all of them constantly trying to take a shower or bath.
