With no warning my mom sims died of laughter. I am so mad.

I've seen that sims taking a bubble bath might be sitting in the tub laughing and having fun long after they are clean. I always keep an eye on someone who takes a bath. Never had a sim die from laughing yet, though.

Another emotion effect that I strongly dislike is that in my student dorm female students get extremely flirty from watching a romantic movie on tv. This leads to female students flirting with everyone, and especially with other females, regardless of being a shy person or what. It simple looks very wrong that a sensible woman suddenly starts flirting like crazy just because she watched tv. Hello??? I've never seen this in homes, but frankly I mostly played students since the DU release.
