Literally same! I don't use any mods, only cosmetic CC. My sims, pre-generated sims, automatically generated, doesn't matter, they all want a shower every 10 seconds regardless of where their hygiene level is at. Trying to manage larger households is terrible!
EDIT - Thanks for the reminder! 🙂
Product: The Sims 4
Platform: PC
Which language are you playing the game in? English
How often does the bug occur? Very frequently, sometimes every ten seconds.
What is your current game version number? 1.103.250.1020
What expansions, game packs, and stuff packs do you have installed? Base game, Desert Luxe, Holiday Celebration Pack, My First Pet.
Steps: How can we find the bug ourselves? Playing in Live Mode with access to a clean, working shower. It should just... happen.
What happens when the bug occurs? All sims, to my understanding, have a very frequent desire to shower and autonomously do it regardless of their hygiene meter's fullness. They hop in the shower for two seconds and hop back out, crossing large lots to find a shower, sometimes repeating the action several times. They break conversations and some actions to go do it almost compulsively.
What do you expect to see? Usually, I believe sims should only autonomously shower when their hygiene meter is getting low, or if they have a related cleanliness trait or a want.
Have you installed any customization with the game, e.g. Custom Content or Mods? I use cosmetic CC for hair and clothing, but no script mods or anything making fundamental changes.
Did this issue appear after a specific patch or change you made to your system? I have only ever had this issue after yesterday's update (05/12/2023).
