Global List borked after upgrade?

I upgraded to 1.1.3 from 1.0.2 to try and fix some issues but it seems to have borked my global list?

I'm using a page with the shortcode [mp_list_global_products] on the main blog. Since the upgrade every "buy now" link just points to the SAME link - the link to the current page?

As a test I tried the shortcode on another page, same result.

First I thought it could be a messy upgrade so I manually deleted all the files and uploaded the new version, still the same.
