The two marked template places (Starting Place and Team/FFA Arena) have their thumbnails become rejected as with the recent change to the thumbnail policy - and many people will see these icons when using studio, which will give an impression of missing care of the ROBLOX Studio product.
Not certain if Studio Features is suited for this, but my reasoning is that the thumbnails are only (mostly) seen for people who use the ROBLOX Studio product, and would otherwise be a Web Feature/Web Bug, as the problem is that the web image assets are rejected.
