Collectible Card Game Headquarters

Describe the Bug:
1- Watcher of the Roost can't be turned face up if you don't own another white permanent.
2- the menu to turn face up asks a "number" card to reveal

Which card did behave improperly ?
Watcher of the Roost

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2014/12/20: Commanding 2014 Urzas,duel

What exactly should be the correct behavior/interaction ?
1- Watcher of the Roost can be turned face up if you only reveal a creature from hand.
2- the menu to turn face up asks for "select a white card to reveal"
Are any other cards possibly affected by this bug ?

Already fixed in dev.
It was a global bug, please check older post before posting reports

In fact I did search and I found the other report about Watcher of the Roost (mentioned in Ruthless Ripper bug report) but because it was mentioned in the other post that: I couldn't morph them until I had cast a spell of the given color.When you select a card to reveal, that card gets discarded instead.
and none of the above happened on Watcher of the Roost I concluded that it was card specific.
