Domain Mapping/Network not working correctly

I'm having a bit of an issue with either Domain Mapping or WP Network handling urls, I'll go ahead and detail the install since its fresh and maybe someone can help me:
scouts.mpressstudios.com - WP Subdirectory Network, has dedicated IP Address.
scouts.mpressstudios.com/pack26/ - Site I'm trying to get configured with Domain Mapping.
http://www.pack26.com - Domain pointing to the dedicated IP for scout.mp.com
It all seems to be forwarding correctly because it takes you to the WP install, but all the urls in the view-source are wrong, "http://www.pack26.comscouts.mpressstudios.com", I've figured out the problem may come from this line in domain mapping:
$return_url[ $this->db->blogid ] = untrailingslashit( $protocol . $domain . $current_site->path );
But not exactly sure how to fix it, any direction would be appreciated.
