Just want to add here - I did not have any problems with any kitchen wall cabinets. In my case it was wall shelves the creator had used moo on to place a lot of decor - like plants and things high on the wall above the windows over the counter. Again not a wall cabinet issue - but a moo issue. There was no CC in the house or in my game, and no mods in my game. All I recall about the house was it was made right after toddlers came out - and was a toddler starter house.
As i said I no longer download houses where the moo cheat has been used period and have not had any further issues like that one since. Definitely no issues with wall cabinets of any size. Right now the only thing in my game that gives me issues is the big round 6 chair dining table from the Laundry day stuff pack. It works fine for my sims to eat at - but they won't clear the dishes from it after eating. I have to physically move the dishes from the table to the kitchen counter to get them to wash them. So the table has an issue - and that is all I see with an issue in my game at all.
ETA One other thing Oldeseadogge - in your house with the issue did you ever have a fire in you sims kitchen? I recall another instance in one of my remodelled Windenburg houses - where I have 3 grown triplet sisters living - one of my main sims sisters had set the kitchen on fire before I had added the sprinkler system to the house. My sim had managed to put the fire out and I thought I had replaced everything burnt and everything appeared fine - but i noticed for the longest time 2 of the triplets kept making faces everytime they came in the kitchen and when I instructed one of them to cook they'd never use the one free counter near the stove but would use the counter near the table in the dining room to make the food. Of course the two good cooks would - but the one lower on cooking skills sometimes would just stop making the food and go to the fridge and grab some yogurt.
After a week of this and I could not see a thing wrong - all I could think was there was soot somewhere I just wasn't seeing - as I recall that was an issue in Sims 2 and 3 - so I hired a maid, as a maid was my solution in the other games. Only this maid instead of finding and fixing the issue waved her hands like something was blocking her in front of the empty counter. I see nothing of course. But I figured it must be something - so I simply moved all the 3 counters on that wall to the middle of the floor and finally saw the issue. Some how the pan that had started the fire on the stove did not vanish when I replaced the stove - somehow it ended up on the floor under the counter the sims would not use. In build mode I could pick the pan up and placed it in the center of the floor. Then back in live mode my sim was able to place it in the trash - I put everything back where it went - and had no further issue. In fact I have never had another issue like it since.
It was like an odd glitch - but figured may as well mention that one too.
Now when ever I do get a sim start a fire - which is extremely rare - I move everything in the room just to make sure nothing glitched underneath something else - just it case. But so far that has been the only time I had that issue. I can also see why two of the sisters in that house made the bad smell face every now and then in that kitchen as well.
