June 27, 2019. Same issue, and it's really, really obnoxious. Is there any way to fix this? Makes it impossible to focus on anything but one family.
Chiming in because this continues to be an issue for me. I play a largish rotational game, and can't remember whose job starts/stops when. I have to stop playing &/or switch households around 4-5 am simtime or sims with night-hour jobs (bartender, criminal) are forced home too early, teens in the barista job miss work, or kids/9-to-5ers miss school or work. This means I sometimes stop playing earlier than I would have, because I don't have enough time to play through a full simday so I can stop at exactly the right simhour. I remember a time when I could stop playing whenever I wished, switch households whenever I wished, & sims would stay at school/work (or instantly return if they briefly showed outside the homelot). It's been months/years since it worked as intended. ( --oh, iirc the simkids tend to lose grade-levels while I'm playing other households, but there's such a large timegap between my 'visits' that I can't say for certain, nor, if this is correct, am I sure it's a connected issue. eta: I see others are experiencing grade-loss also.)
