[fixed/closed]Victual Sliver no lifegain when sac'ing itself

[Nexhro]

Describe the Bug:
When Victual Sliver is sacrificed to the ability granted by it, its controller doesn't gain any life. Sacrificing other Slivers works fine.

Which card did behave improperly ?
Victual Sliver

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
CoRM15 mini3, duel

What exactly should be the correct behavior/interaction ?
When Victual Sliver is sacrificed to the ability granted by it, its controller gains 4 life.

Are any other cards possibly affected by this bug ?
Also tested Acidic Sliver -> same bug

Likely also affects other (Sliver) creatures with activated abilities that rely on global legacy effect cards.

Fixed for this and for all the other Slivers with similar abilities.
