at one point I could choose (for free) some campain mission with giants. I played thru it and enjoyed it. now when I log on to play it asks me if I want to continue if I say yes I play in the middle (different games each time) some game with the giants. and if I win it asks me again if I want to continue where I left on some of the games with giants. If I say no I and then try to start up a game I cant find the giant cards any where.
