Anyone else ever get some...really disquieting glitches?

One of my sims had two much younger siblings that she took care of once the parents passed away. She got married and and started a family of her own while her brother and sister were still kids, so it was quite a full household lol. But then I started to notice...her husband kept getting a whim to flirt with her little brother. Who was a child. I just ignored it, clearly a glitch, BUT IT JUST KEPT HAPPENING. When her brother aged to a teen and it kept going on, I couldn't take it any more. I had her divorce hi and moved him out, it was just so distracting to try and play this Big Happy Family thing with sim when her husband kept lusting after her underage brother!

So, anyway, I was just wondering if anyone else had any similar stories, lol? Any bugs in your game that were less funny and more...icky?
