Collectible Card Game Headquarters

Describe the Bug:
Dimir Keyrune at least by AI can be made to produce loads of mana.

Which card did behave improperly ?
Dimir Keyrune

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2014/10/20: Conspiracy for the recoding of M15 minipatch 5,duel

What exactly should be the correct behavior/interaction ?
Dimir Keyrune

Are any other cards possibly affected by this bug ?
all Keyrunes?

Confirmed. In a clean game I saw an AI cast Ghastlord of Fugue using just a Dimir Keyrune and 2 City of Brass.

Also tested with Boros Keyrune and Nobilis of War and had the same result. Probably all keyrunes.

It appears that the keyrune always becomes a creature and that the AI needs 2 mana to make it a creature in order for this to work. I am going to guess that the adding mana ability choice is being responded to somehow by the AI and is not limited by needing to tap, so it just adds as much as it wants. The player can't seem to do this.
