Sitemap issue with categories as sub-domains

I've set up my categories to act as subdomains, simply because it makes the place more organized and Oleg has been a tremendous help with getting this set up and running.

The problem with the sitemap is that instead of http://category.domain.ext I am getting this inside the sitemap: http://domain.ext.http://category.domain.ext It does redirect to the correct page though, but I was wondering if there was a way to correct this?

I also currently have the community offline so that I can refine most of the categories. But I do every now and then open it up for some testing purposes (Running as a regular registered user) that I can't do while as an Administrator.

Hello,
