Collectible Card Game Headquarters

Describe the Bug:
- Sunscour can't be cast normally for 5WW (mana is rejected into mana pool)
- If there is 2 white cards in caster hand, if RFG option is chosen game will ask for 2 black cards (2 white cards can still be chosen), if caster hit the cancel button the spell will still resolve

Which card did behave improperly ?
Sunscour

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Jan 01, 2014 : Commanding the revision of Ice Age v2 - DUEL

What exactly should be the correct behavior/interaction ?
- Sunscour can be cast normally for 5WW
- If there is 2 white cards in caster hand, if RFG option is chosen game will ask for 2 white cards, if caster hit the cancel button the spell will not resolve

Are any other cards possibly affected by this bug ?
-

It cast correctly for me (both removing cards from game and for mana). However, it does ask for black cards.

No longer getting an option to exile white cards instead of paying casting cost.

casting by discard is bugged (and is for similar cards too). Not all cards in hand are displayed for you to choose from and cards that are actually removed are not the ones chosen.

Sounscour can not be cast now neither for normal cost nor for alternative cost.
