When I go to meta.gaming.stackexchange.com, I am redirected to the login page on gaming.stackexchange.com (the "meta." has been dropped). After logging in, I am still in the non-meta site. I should have been redirected back to the meta site, since that's where I was trying to go.
Furthermore, I am on the non-meta login page, which makes it look like I haven't logged in (except for the fact that I now see my user name at the top of the screen).
