Collectible Card Game Headquarters

Describe the Bug:
If there are no creatures in the graveyard of the player chosen for Teneb, the Harvester's triggered ability, that ability's controller is stuck in the graveyard viewer. There's no option to cancel the ability as clicking an invalid target has no effect on the game asking said controller to select a target.

Which card did behave improperly ?
Teneb, the Harvester

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
C14U, gauntlet

What exactly should be the correct behavior/interaction ?
The ability can be cancelled after a player has been chosen.

Are any other cards possibly affected by this bug ?

The above can only happen if there is a creature in a graveyard (otherwise the ability when activated doesn't open menu at all) and you select the other graveyard.If it opens you automatically only the 1 with the creature in it like many of these cards work like that then no problem.
