I was working on them a while back before I threw in the towel because I got annoyed tracking parts down. I've been playing World of Warcraft pretty much ever since. I have gone back to SO6 for a little bit but I'm working on a new schedule at the moment. Debating how I want to tackle the horse skins, but I intend to go back to them eventually. I'd be happier if the tack was separate from the horse, though. Make tracking things down a lot easier.
Also would be nice to have different saddle cloths for each number rather than specific to horse color, but that's a pipe dream currently.
