[fixed/closed]Cavern Harpy multiple activations

[Aswan jaguar]

Describe the Bug:
1- Cavern Harpy can be activated multiple times in stack by AI at least(if not a bug certainly a bad behaviour)
2- When activated multiple times in stack back in hand return as many copies as the activations.

Which card did behave improperly ?
Cavern Harpy

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
2014/05/06: Journey into Nyx

What exactly should be the correct behavior/interaction ?
1- AI doesn't activate Cavern Harpy activated ability more than once in stack.
2- Only the original returns to hand when the last activation in stack resolves first if it is activated multiple times.The other activations don't find target to return.

Are any other cards possibly affected by this bug ?
