[still bugged]Drain Power-Mirari's Wake,City of Brass intera

[Nexhro]

Describe the Bug:
Mana added to a player's mana pool by Drain Power doesn't empty from that mana pool as steps and phases end.

That mana is emptied from that mana pool on the phase/step after that player added mana to his/her pool while not casting spell.

Which card did behave improperly ?
Drain Power

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

What exactly should be the correct behavior/interaction ?
Mana added to a player's mana pool by Drain Power empties from that mana pool normally.

Are any other cards possibly affected by this bug ?

It also gives you mana for each land target player controls, even if it is tapped.

Basically works as intended, but...

I don't know if this is an issue with the mechanics or what, but if a City of Brass is possessed by the targeted player and is tapped for mana due to Drain Power the player does not loose 1 life (other triggers off land tapping were not tested).

Drain Power also doesn't take into account cards like Mirari's Wake/Mana Reflection (when controlled by Drain Power's controller's opponent).

Interesting that the interaction with Mana Confluence works properly.
