Collectible Card Game Headquarters

Describe the Bug:
In the attached save, the AI hangs when it draws a Cloud of Faeries with an Izzet Boilerworks in play.

It's possible the Grim Monolith has something to do with it, but I don't think so; force-burying the Izzet Boilerworks is enough to make it proceed normally. edit by Aswan jaguar the problem is Compulsive Research.

Which card did behave improperly ?
Cloud of Faeries

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
KOT, challenge mode

What exactly should be the correct behavior/interaction ?
It shouldn't hang.

Are any other cards possibly affected by this bug ?
I would assume this affects all untap-lands-on-cast spells and all lands capable of producing more than one mana (or effects that make lands produce more than one mana.)

The hang is confirmed for another card though, Compulsive Research is the problem for AI.The peculiar thing is that the first 2 times I loaded the savegame there was no hang whatsoever from the 3nd time and on everytime it hanged.Mysterious the ways of AI.I don't remember if AI used Compulsive Research those first 2 times,though.

I'm checking it now and don't seems to crash for me when played by the AI, so I guess it's already fixed in dev.
