Since the patch, I've found a bunch of spoiled food in the fridge. I can't prove this was related to the patch, but the spoiled items had only been in the fridge a couple of days, and it's an expensive fridge so I wouldn't have expected things to spoil this quickly. I didn't find out about the problem until after my poor Sims had eaten the spoiled food and gotten sick, so if you have leftovers you might want to check before your Sims eat them.
