Housing leaderboards are still broken. I'm told that they got mucked up when the marketplace was turned off, and that a relist should fix, but it doesn't. There are zero homes showing on the leaderboards in any category, even when you go into a home that says it is listed. Cloudrat relisted hers to no avail, it still doesn't show. My depot display setup says it is published, and doesn't show in medium homes.
Yes, the marketplace on beta was turned off on purpose. This is currently affecting beta copies and leaderboards. The next update will fix those issues (although the marketplace itself will remain disabled for now).
