[fixed/close]offering mechanism doesn't count colorless mana

[Aswan jaguar]

Describe the Bug:
1- Offering ability has a global bug that doesn't take into account either the non-coloured mana when subtracting the mana of the offer creature to cast the new or doesn't take into account mana of the offer.
tested Patron of the Akki and Patron of the Kitsune
2- see EDIT
Which card did behave improperly ?
offering mechanism

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
16/11/2013 : Portals to Theros - DUEL

What exactly should be the correct behavior/interaction ?
All the mana coloured and non-coloured (evaluating coloured to subtract coloured if needed)from card offered has to be subtracted from the card with offering that is cast.

Are any other cards possibly affected by this bug ?
Patron of the Akki
Patron of the Kitsune
Patron of the Moon
Patron of the Nezumi
Patron of the Orochi

EDIT - Also creatures playing offering can't be cast instantly.
I have reported also Patron of the Nezumi few months ago:
