This is new to me, but it may not be to you seasoned veterans: while my sim was meeting Spar Tournament opponents at their vacation home in China, her husband passed the time by swimming in their pool, off and on all day. Then they went into the mountains to fish for a few hours. I sent him home while she stayed behind to catch some more dragonfish. When she got back home, he was still in the pool, had the fatigued moodlet, and a drowning moodlet (!!) with 32 minutes remaining. I had never seen that before! Do we need to watch our sims when they swim to ensure their safety?
