Unhappy because house poorly decorated

I'm also getting this moodlet, but curiously only when my sims enter restaurants. I redecorated the entirety of the Diving Pelican Maxis prebuilt and my sims were still getting uncomfortable from the decor. Maybe this is an anomaly but even after adding paintings, decorations, and other expensive items they kept the uncomfortable from poor environment moodlet.

One other thing I've noticed when playing my rags to riches save is that sims now get the uncomfortable from poor environment moodlet when the walls are still drywall! I think that makes sense and I've never had that occur before.
