This has been reported several times on these forums and now on the US forums (as they have a website bug reporting section). In fact someone actually moved one of the times it was mentioned in Customer Support, to the General Discussion section.
It’s not us. It’s you. Or … more correctly, the website. It has had a bad link on it since the new expansion was announced when, I’m assuming, the website had a copy/paste update from the US site, and no-one has bothered to fix it since to work for those of us in the EU.
