Collectible Card Game Headquarters

Describe the Bug:
Not sure what triggers it, but sometimes not all permanents targetted by Brago, King Etrnal's triggered ability are exiled/returned. Permaments not exiled this way have permanent crosshairs on them.

Which card did behave improperly ?
Brago, King Eternal

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

What exactly should be the correct behavior/interaction ?
All targetted permanents are blinked.

Are any other cards possibly affected by this bug ?
-

Muzzio was a deciding factor in a clean game as well.

The problem is the interaction with our implementation of the "Legend rule". I'll see what I can do.
