[confirmed]AI-Devouring Strossus regenerate sac itself

[Aswan jaguar]

Describe the Bug:
AI blocked with Devouring Strossus my golem from Tuktuk the Explorer which was pumped by Virulent Swipe after getting blocked, then AI regenerated Devouring Strossus by sacrificing itself (AI had no other creatures) although a non target sign was put on Devouring Strossus.Then on AI's turn AI didn't sacrifice Devouring Strossus (AI's only creature) because of that sign?

Which card did behave improperly ?
Devouring Strossus

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2015/3/25: Fate Reforged,duel

What exactly should be the correct behavior/interaction ?
Devouring Strossus can't regenerate by sacrificing itself.

Are any other cards possibly affected by this bug ?
