Collectible Card Game Headquarters

Describe the Bug:
With Dack Fayden 's ultimate emblem in play, it generates a legacy "Gain control of target permanent" card if you target a player with a spell.

Technically this should only trigger when you target permanents, and players are obviously not permanents. I don't think this is actually causing any errors, but it makes a legacy card sit around on the battlefield not attached to anything.

Tested using cards such as Ancestral Recall, and Inquisition of Kozilek.

Which card did behave improperly ?
Dack Fayden

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
M15 mini patch 3 sept 2014

What exactly should be the correct behavior/interaction ?
Dack Fayden - only when targetting permanents

Are any other cards possibly affected by this bug ?
NA

Targeting a player with Fire||Ice (for both points of damage) caused a dump to occur with Dack Fayden 's ultimate in play. It actually produced quite a few but here is the last from the log.

After some more testing it seems to dump whenever multiple things are targeted by a single spell with the ultimate in play. In many cases, soft locking the game.
