posted precons that have non working cards

trying out the garruck/liliana deck that is available in the precon decks zip. get an error message that 'fleshbag marauder' is not working properly or bugged. why is this deck released as functioning if it contains cards that don't work?
...checking more precons. it seems every one of them has non working bugged cards. does anyone know why these decks are posted for release when they don't fully function?
