So, I was still wondering why this very cute looking home, that fits so nicely into Sulani, didn't get any downloads. I tried to find it in the gallery under 'Grier House' but it did not come up. I then went by your user name and opened your catalogue which is where I found it. But do you realize this lot is showing up as including custom content? This is what the little wrench symbol indicates:

This means the lot does not show up when players scroll through the gallery or even in their searches unless they tick the 'Include Custom Content' box in the the search options. I don't know about you, but I never do that. If you didn't actually use any CC in your build, the most likely culprit are pictures taken of or by your Sims that are somewhere in the house.
