Collectible Card Game Headquarters

Describe the Bug:
Cards with bestow ability can't be cast normally if you have on the battlefield enough mana to play them with bestow BUT some mana is tapped and you want/can cast them normally.The engine will highlight them as castable will ask for the correct amount of mana but it will not let you cast them and the mana will rejected to mana pool.
The savegame is for Nyxborn Wolf but I have noticed it with many more bestow cards.
ex. You have a Nyxborn Wolf on your hand, lands on the battlefield and a Squire but you have tapped land and you can't play bestow but want to play it normally then you are not able.
Which card did behave improperly ?
bestow ability

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
2014/02/18: Born of the Gods v2 - DUEL

What exactly should be the correct behavior/interaction ?
ex. You have a Nyxborn Wolf on your hand, lands on the battlefield and a Squire but you have tapped land and you can't play bestow, you are able to play it normally.

Are any other cards possibly affected by this bug ?

Trying to cast it normally (at least Nyxborn Wolf) either in the above condition or if you don't have enough mana for bestow asks for mana twice.
