Collectible Card Game Headquarters

Describe the Bug:
Artifacts and creatures (and lands) don't untap when Winter Orb is on the battlefield.

Players get to choose one land to untap per turn as intended.

Which card did behave improperly ?
Winter Orb

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

What exactly should be the correct behavior/interaction ?
Artifacts and creatures are not affected by Winter Orb.

Are any other cards possibly affected by this bug ?
Rising Waters works fine.

That's strange, since Rising Waters and Winter Orb shares the same global function.
However, fixed in b71e5e1

But,they have different code pointer,though.

Only affects lands as of CoRM15 mini2. Fixed.
