[fixed/closed]Backfire triggers off creatures

[Nexhro]

Describe the Bug:
When a creature enchanted by Backfire deals damage to a creature controlled by Backfire's controller, Backfire deals that much damage to the enchanted creature's controller.

This goes for combat and noncombat damage (tested with Thrashing Wumpus).

Which card did behave improperly ?
Backfire

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

What exactly should be the correct behavior/interaction ?
Backfire only deals damage to the enchanted creature's controller when that creature deals damage to Backfire's controller.

Are any other cards possibly affected by this bug ?
