I'm not sure if it's intended or not, but you have to log out and log back in to get the card bonus.. at least I did when I got my first one.
Should be fixed since 1 or 2 patches, but i noticed it myself, sometimes it doenst change in realtime, you need to swap wordls or relogg.
doesn't fixed yet and refresh dont hurt anyone so JUST DO IT :v
OK, just thought I'd point it out in case it wasn't 'on the list' yet
