Collectible Card Game Headquarters

Describe the Bug:
When I sacrifice Zealous Conscripts (or any other creature I've tried) to Scourge of Skola Vale, the latter doesn't get any +1/+1 counters.

Which card did behave improperly ?
Scourge of Skola Vale

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

What exactly should be the correct behavior/interaction ?
When a creature is sacrificed to Scourge of Skola Vale's ability, a number of +1/+1 counters equal to the sacrificed creature's toughness is put onto Scourge of Skola Vale.

Are any other cards possibly affected by this bug ?
-

Already fixed.

Doesn't get any counters as of BFZ.

Different bug, same symptom. The underlying interface changed since then, making it much harder for client code to find out what was sacrificed. Sigh. Fixed with a horrible, horrible hack in 51e8f36.
