[fixed/closed]Umbra Stalker bad P/T check

[Nexhro]

Describe the Bug:
Umbra Stalker seems to have problems with recognizing the number of black mana symbols on certain cards.

For example, a Worm Harvest in its controller's graveyard adds no P/T at all to it while a Creakwood Liege in the graveyard gives it +2/+2 instead of +3/3.

Whether the bug is limited to hybrid spells or not is unclear.

Which card did behave improperly ?
Umbra Stalker

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
CoRM15 mini5, duel

What exactly should be the correct behavior/interaction ?
Mana symbols are counted correctly.

Are any other cards possibly affected by this bug ?

Batwing Brume isn't counted either.

Well, this was a global bug: it was counting only the colored mana symbols of permanents, so Sanity Grinding was bugged too.
