Hi everyone, I believe this bug is not specific to the latest software update, but something that has crept in in the last few updates. 

I have a house of 8 sims, and the house is designed to keep certain sims from interacting with each other (they flirt uncontrollably and cause all kinds of problems). To keep them apart (and alive), I have sections of the house that specific sims have no access to, and a total of three kitchens that are designated to different sims (through locked doors). What I'm starting to notice the last few weeks is that at least one fridge will quietly lock itself out halfway through a game session, and a sim that has access to a particular kitchen will start waving its hands whenever I try to get it to cook food, as if it has no access to the fridge that it was standing right in front of. Since I don't have the time to check on every one of them all the time (i'm trying to get a few of my younger sims to level up in skills and complete aspirations), I have already have so far 4 to 5 deaths (through starvation) in the house, as a result of sims insisting to reach for a fridge that they have no access to. What's odd is that the affected sims (or fridge?) can still open the fridge designated for them for glasses of water, milk and off-brand soda, but they don't have access to any of the "actual" quick meals (ham sandwich, cereals, apple sauce etc). It's like as if the game thinks I'm trying to starve the affected sims to death and kills them for me. The process of resurrecting them is a pain - wishing well, angel fish, death flower, potion of youth, the usual.

Anyone having the same issue? 

I’ve noticed they’ll sometimes try to go to the one that’s closest as the crow flies, not as they actually path. So for example if you have two kitchens next to each other, and your sim is standing in one, next to the wall where the fridge they can’t access is directly on the other side (or directly above or below it in another floor), they’ll say they can’t reach it - but if you walk them away from that spot first then they’ll go to the fridge they can access. Is that possibly in play here at all? Though I can’t imagine how they’d never get near enough, unless they just stand in one spot constantly trying and failing to go to the wrong fridge until they die...

Or the opposite problem, and it’s a new & deadly variation of https://answers.ea.com/t5/Bug-Reports/OPEN-Sims-Use-Far-Away-Sink-for-Dishes-instead-of-Close/

Hi Pip Menace, thanks so much for the quick reply. So far I think I've tried two different kitchen layouts, one is where the kitchens are next to each other (the fridges are only separated by a layer of wall) and one is where they are on opposite ends of the lot (this is a 40x30 lot). I've been avoiding multi-storey lots cause it's harder to manage my sims when I can't see what they're up to. Doesn't seem to make any difference to me, for now. The way my current lot is designed is that each group of sims would have their own areas (with amenities at the furthest corners to keep them from getting confused). Seems like the only way to fix the bug for now is to simply save, exit and reload the game, but the problem here is I usually don't know the fridge has locked up (and yes, the hungry sims go away for awhile and will return to their fridge, and they will repeat the process a few times until their 48 hours are up before dropping dead - usually right in front of the fridge). So unless i'm actively checking and clicking on any hungry sims and make them cook their food I won't know they can't access food until they are dead. Since lots of aspirations can be completed in 48 hours, reverting to the previous save is usually not an option for me, and my current PS4 Pro is getting really slow for game save every 10 minutes. I'm tempted to upgrade my console's HDD to SSD but that's not something I want to do for the time being considering the cost of a 2TB SSD, and not knowing if the upcoming PS5 will support Sims 4 or not. 

I guess my gripe here is that the game indicates that when sims are fully automated, they have a fail safe built-in i.e. they won't allow themselves to starve to death. But the way the sims are behaving lately is suggesting that this fail safe is not working, and it is killing them.

And yes, I have the same sink bug as well. A sim would eat its food in the kitchen and walk to a bathroom on the other side of the lot to wash the plate, when there's a sink right next to it.
