[Plugin: WordPress MU Domain Mapping] Mapped Domain loads entire theme from main site

Hi,

I’m running WordPress 3.0.1 with Domain mapping 0.5.2, with these options enabled:

Permanent redirect (better for your blogger’s pagerank)
User domain mapping page

Whenever I run a scan on http://tools.pingdom.com against my mapped domains I notice it not only loads that site’s theme but also the entire theme from the main site.

Any idea how I can solve this and only have it load the mapped sites theme?
