When I start a game it is always based cards game (example game #158 ).
If I try to bias with unckecking Bases cards in the "Select Kingdom cards" window, I have a alert on the start of the game saying : "More cards required than available".
Relog into the game, should be fine now.
If you log out & back in again you will own all sets.
It's a bug now that new accounts end up with base only. I just fixed it in the database for all existing accounts, but to fix new ones we'll need a new release
Yes it works !
