Collectible Card Game Headquarters

Describe the Bug:
If there are more then one Splinterfright in play and you gy is emptied only one Splinterfright dies (and sometimes not even 1)

Which card did behave improperly ?
Splinterfright

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
2014/02/18: Born of the Gods v2 - DUEL

What exactly should be the correct behavior/interaction ?
When the gy is emptied the Splinterfright 's toughness should hit 0 and he should die (and this should happen to all in play simultaneously).

Are any other cards possibly affected by this bug ?
Sewer Nemesis

I tested with 2 or more Splinterfright in battlefield and a creature or more in graveyard as soon as I cast Timetwister or used Feldon's Cane 's ability to empty graveyard 1 goes to graveyard and the others live because they don't die simultaneously.

That's the usual Manalink problem... I'll try to devise a workaround but no promises.
