Sims' computers have gone missing

Not sure is this is an official bug, or just something happening in my game, but at least with one house in the past few real-life days, my Sim's computers have gone missing! 😮 I click on their computer to have them do something and the computer vanishes.  It is not in their personal inventory, nor is it in the household inventory.  I do not have CC or Mods.  At least one of the times I had an action queue lined up; (eg. use bathroom, play computer game, sleep, shower).  That time the Sim just went to the bathroom and went to bed and skipped playing the computer, probably because it disappeared when I clicked on it.  So far it has only happened in one household.  I just wanted to know if this has happened to anyone else, and if so, do y'all know how to fix it? 🤔  Thank you! 🙂
