I decided to work on the ice furniture for my Glass House of Water project. I plopped the house down in my new world, and filled it with 8 sims who are going to get awfully good at sculpting. Right away I noticed they were getting the negative "Unfinished walls/floor" moodlet. I should point out that the actual pool portions of the house are outside. I did test it before I saved it to my library, and I'm pretty certain my test sim didn't get the moodlet.
I did some googling, and it seems there might be an issue with using the pool wall/floor inside. I had been using them make the whole thing look like a giant pool, but I decided to replace the pool tile with paint and carpeting. This did get rid of the moodlet. I tried replacing the pool tile, and the moodlet came back. I went back to the replacements, and everything was fine.
So, now my house is fully carpetted and painted, even the actual pool portions because I wanted everything to match (yep, this house has the super luxurous carpetted pool feature all sims appreciate so much). But I would rather have the original pool tile I used. Has anyone encountered this issue, or have any ideas on how to resolve it and keep the pool tile?
