[fixed/closed]Slivers bad tap abilities

[Nexhro]

Describe the Bug:
1) Slivers that grant tap abilities to all Slivers create legacy effect cards.
These legacy effect cards can be activated an infinite number of times for the same creature. For example, I can tap Galerider Sliver for Magma Sliver's ability again and again, despite it being tapped after the first activation.
I succesfully reproduced this with Magma Sliver, Screeching Sliver, and Psionic Sliver.

2) Slivers with summoning sickness can be tapped to activate one of those legacy cards (again and again).

Which card did behave improperly ?
At least Magma Sliver, Screeching Sliver, and Psionic Sliver.

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

What exactly should be the correct behavior/interaction ?
Summoning-sick creatures and tapped creatures can't be tapped to activate an activated ability that requires tapping.

Are any other cards possibly affected by this bug ?
Also tested Manaweft Sliver and Gemhide Sliver (which don't use legacy effect cards) -> no bug

Likely also affects other Slivers that grant tap abilities to Slivers.

Fixed.

Summoning sickness is fixed, but you can still 'use' a tapped sliver over and over.
