Only to fix technical problems. After an item is released, Highrise can fix bugs such as layering or missing parts, but it doesn't make style changes. Ask for design changes during production, while you're reviewing previews.
What can be fixed after release?
Layering problems, such as an item showing over or under the wrong things, within technical limits

How do I get changes made before release?
During production, the art team sends you previews in your Concept or Idea chat. That's the time to ask for changes. Give feedback within 24 hours of each preview, and send it in the chat itself. See My Idea was funded. What happens next? or What do I get if my Concept wins?
