We would like to recommend you unofficial patch. You can download it here:

It will fix most common WBC 3 bug.
Enjoy :)

I add to the card sentence "This game has been patched to the latest version 1.03.24".
That means that we've got official approval for this patch :)
Now, the game you can download from "my account" page is patched latest patch version with all bugs fixed and you don't have to do nothing except play :)
I hope that's a good news :)
