[fixed/closed]Sigil of Sleep

[client h]

Describe the Bug:
Sigil of Sleep shows some strange behaviour. When I attack with 1 creature, enchanted with Sigil of Sleep, and I do damage opponent the ability is triggered. When I attack with 2 creatures, one enchanted with Sigil of Sleep, the ability is not triggered and with 3 creatures sometimes it is and sometimes it ain't. Ofc in all instances I do damage opponent with the creature enchanted with Sigil of Sleep.

Which card did behave improperly ?
Sigil of Sleep

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

What exactly should be the correct behavior/interaction ?
Everytime I damage an opponent with a creature enchanted with Sigil of Sleep it's ability to send a target creature to that players hand should be triggered, no matter with how many creatures I attack.

Are any other cards possibly affected by this bug ?
No.

I confirm this partly as it seems that it triggers Only if the enchanted creature attacks alone.I couldn't reproduce that it happens with 3 creatures attacking.
