I've seen this on PS4. I had a sim knit a "Forbidden Sweater" and after she finished her energy was severely depleted. Her energy gain was stuck at 1 arrow during sleep and her hunger and bathroom started going down quickly, as if she was a toddler instead of an Elder Sim.
After shutting down my console for the night, the next day she was back to normal after loading the game again.
Edit: I had this happen without knitting the forbidden sweater, so that may have just been a coincidence.
I've tried logging on and off again, changing characters, moving house.
All to no avail. My sim can't work because sleeping takes 14hrs showering takes 4hours. Seriously urgent issue!!
