[NEEDS SAVES] [CL] Sim dying from bad pufferfish Nigiri despite not eating any

Product: The Sims 4
Platform:Mac
Which language are you playing the game in? English
How often does the bug occur? Often (50% - 99%)
What is your current game version number? SP41.31
What expansions, game packs, and stuff packs do you have installed? All except goth kit, bistro kit, and pool lounge kit.
Steps: How can we find the bug ourselves? My sim (to my knowledge) NEVER ate pufferfish nigiri, but keeps dying from it at random after eating other cooked meals. She cooked it poorly once, but another sim in the household ate it. I believe she was pregnant at the time, so if she had been queued to eat it that might be the source of the bug—she never died and now it triggers randomly since she's no longer pregnant. She doesn't die after every meal, but garden salad, grilled cheese, and berry waffles among others (On multiple different lots) have triggered the "from pufferfish" poisoning death.
What happens when the bug occurs? The sim dies from bad pufferfish nigiri despite eating a different cooked meal. She eats, the death triggers, and I have to revive her in order to keep playing.
What do you expect to see? The sim does not die from eating regular cooked meals.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure

The only mods I use are cosmetic (Loading screen color change) and CAS items like makeup, hair and clothes. There is no pufferfish in her inventory nor in the fridge. She has moved household lots since the error began happening.
