Not using any mods in my game ☹️
Could you start a new save game for testing purposes to see if you have the same issue on a fresh game as well or if it's save game related.
Sorry for the slow response, work has taken much of my time this week.
Have tested with another save for a few hours and the same thing happens. They are all disobedient sims!
Try resetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199
You won't loose anything. Just make sure to not delete any files and make a backup.
Try on a new game with nothing added back first (start new game). If it works, put back your save game and try again. If it still works, you can start putting stuff back.
The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game.
