I hate how sims don't progress in their careers with story progression or have poor performance.
I had my current sim visit a household I used to play. This sim was in the daycare career. There were two toddlers on the floor, crying. I thought she and her husband had kids (even though they were both elders), when I moused over them, it read "[Toddler] is terribly moody!" Did I mention this was late at night? So somehow, my previous household is apparently stuck with two daycare toddlers.
