[waitlisted]Nefarious Lich vs Moment's Peace and co

[Aswan jaguar]

Describe the Bug:
1- Nefarious Lich exiles cards from your graveyard even when you deal the damage so protects opponent from damage,too.(at least when owned by AI).
2- It exiles only 1 card per source of damage.
3- The cards that get exiled don't appear on the exile zone.
4- I don't think it works well with other effects that prevent damage.I attacked to AI (AI had Nefarious Lich) and then I played Moment's Peace to test it and AI still exiled a card due to Nefarious Lich.Is this correct?
5- Also AI attacked with 3 creatures and had 2 cards in Library and probably because of that a series of 6 errors occurred.
6- (minor)If you disenchant it,return to library,etc you win the game but Nefarious Lich still appears on the battlefield.
Which card did behave improperly ?
Nefarious Lich

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
2014/02/18: Born of the Gods v2 - DUEL

What exactly should be the correct behavior/interaction ?
1- Exiles cards only when You are dealt damage and prevents Only damage to you not opponent.
2- Exiles as many cards as the damage you are dealt.
3- Exiled cards show on exile zone.
4- ?
5-
6- (minor)Nefarious Lich has to leave the battlefield (visually at least it doesn't)for the effect to take place.
Are any other cards possibly affected by this bug ?
