[fixed/closed]Mercurial Pretender crashes game

[Nexhro]

Describe the Bug:
When Mercurial Pretender is cast, it is put into its owner's graveyard before prompting its controlelr to choose a creature to copy.

When a creature is chosen this way, the client crashes.

I've seen the Ai use it as intended (creature was copied, no crash).

Which card did behave improperly ?
Mercurial Pretender

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

What exactly should be the correct behavior/interaction ?
Mercurial Pretender copies the chosen creature without crashing the game.

Are any other cards possibly affected by this bug ?
