My Sims No longer Like The Decor??!!

The more I read about what the two of you have said about having this issue with new homes that you had moved your sim family into, and what I went through in my saved games over the years. I think that this glitch is a core related glitch. The fact is this, in both cases, sims are suddenly feeling different about their surroundings with no apparent cause to the issue that's noticeable. For me this issue of my sims suddenly feeling that they are in a dirty kitchen started right after we had gotten Dine Out. In my case, I thought that it was an issue with the new dishwashers that came with Dine Out. So I replaced every thing that was in the kitchen, starting with those and no change. Now I don't know when this issue started in your games.
ETA: In my case, it's cross-platform. In my case, this issue has been occurring in my saved games on both PC and PS4.
