Buggy source:
@Override public boolean moveCardsToGraveyardWithInfo(List<Card> allCards,Ability source,Game game,Zone fromZone){
  while (!allCards.isEmpty()) {
    Cards cards=new CardsImpl();
    UUID ownerId=null;
    for (    Card card : allCards) {
      if (cards.isEmpty()) {
        ownerId=card.getOwnerId();
      }
      if (card.getOwnerId().equals(ownerId)) {
        cards.add(card);
      }
    }
    allCards.removeAll(cards);
    if (cards.size() != 0) {
      TargetCard target=new TargetCard(fromZone,new FilterCard("String_Node_Str"));
      target.setRequired(true);
      Player choosingPlayer=this;
      if (ownerId != this.getId()) {

Fixed version (ground truth):
@Override public boolean moveCardsToGraveyardWithInfo(List<Card> allCards,Ability source,Game game,Zone fromZone){
  while (!allCards.isEmpty()) {
    Cards cards=new CardsImpl();
    UUID ownerId=null;
    for (    Card card : allCards) {
      if (cards.isEmpty()) {
        ownerId=card.getOwnerId();
      }
      if (card.getOwnerId().equals(ownerId)) {
        cards.add(card);
      }
    }
    allCards.removeAll(cards.getCards(game));
    if (cards.size() != 0) {
      TargetCard target=new TargetCard(fromZone,new FilterCard("String_Node_Str"));
      target.setRequired(true);
      Player choosingPlayer=this;
      if (ownerId != this.getId()) {
        choosingPlayer=game.getPlayer(ownerId);
      }
      if (choosingPlayer == null) {
        continue;
      }
      boolean chooseOrder=true;
      if (cards.size() > 2) {
        chooseOrder=choosingPlayer.chooseUse(Outcome.Neutral,"String_Node_Str",game);
      }
      if (chooseOrder) {
        while (choosingPlayer.isInGame() && cards.size() > 1) {
          choosingPlayer.chooseTarget(Outcome.Neutral,cards,target,source,game);
          UUID targetObjectId=target.getFirstTarget();
