Collectible Card Game Headquarters

Describe the Bug:
A creature put onto the battlefield from the opponent's graveyard via Extract from Darkness instantly vanishes (presumably gets exiled) upon entering the battlefield.

Creatures put onto the battlefield from Extract from Darkness's controller's graveyard stay on the battlefield as intended.

Which card did behave improperly ?
Extract from Darkness

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
CoRM15, duel

What exactly should be the correct behavior/interaction ?
Creatures put onto the battlefield via Extract from Darkness stay on the battlefield (sans toughness-decreasing static abilities etc) no matter what graveyard they were put onto the battlefield from.

Are any other cards possibly affected by this bug ?
-

This is really strange, could you check again in a clean game ?

Confirmed in a clean game. Creature disappears and doesn't appear as exiled.

There was a global bug in the 'new_global_tutor' function, is fixed in 4a436f3.
Bugfix minipatch out this weekend.

Works properly with creature cards from either player's graveyard as of CoRM15 mini2.
