Buggy source:

  Player controller=game.getPlayer(source.getControllerId());
  Permanent sourceObject=game.getPermanentOrLKIBattlefield(source.getSourceId());
  if (controller != null && sourceObject != null) {

    if (defendingPlayerId == null) {
      Logger.getLogger(MyriadEffect.class).error("String_Node_Str" + sourceObject.getName() + "String_Node_Str"+ (sourceObject.isAttacking() ? "String_Node_Str" : "String_Node_Str"));
      return false;
    }
    List<Permanent> tokens=new ArrayList<>();
    for (    UUID playerId : game.getState().getPlayersInRange(controller.getId(),game)) {
      if (playerId != defendingPlayerId && controller.hasOpponent(playerId,game)) {
        Player opponent=game.getPlayer(playerId);
        if (opponent != null && controller.chooseUse(Outcome.PutCreatureInPlay,"String_Node_Str" + sourceObject.getIdName() + "String_Node_Str"+ opponent.getName()+ "String_Node_Str",source,game)) {

          effect.setTargetPointer(new FixedTarget(sourceObject,game));
          effect.apply(game,source);
          tokens.addAll(effect.getAddedPermanent());
        }
      }
    }
    if (!tokens.isEmpty()) {
      ExileTargetEffect exileEffect=new ExileTargetEffect();
      exileEffect.setTargetPointer(new FixedTargets(tokens,game));
      game.addDelayedTriggeredAbility(new AtTheEndOfCombatDelayedTriggeredAbility(exileEffect),source);
    }

Fixed version (ground truth):
@Override public boolean apply(Game game,Ability source){
  Player controller=game.getPlayer(source.getControllerId());
  Permanent sourceObject=game.getPermanentOrLKIBattlefield(source.getSourceId());
  if (controller != null && sourceObject != null) {
    UUID defendingPlayerId=game.getCombat().getDefendingPlayerId(source.getSourceId(),game);
    if (defendingPlayerId == null) {
      Logger.getLogger(MyriadEffect.class).error("String_Node_Str" + sourceObject.getName() + "String_Node_Str"+ (sourceObject.isAttacking() ? "String_Node_Str" : "String_Node_Str"));
      return false;
    }
    List<Permanent> tokens=new ArrayList<>();
    for (    UUID playerId : game.getState().getPlayersInRange(controller.getId(),game)) {
      if (!playerId.equals(defendingPlayerId) && controller.hasOpponent(playerId,game)) {
        Player opponent=game.getPlayer(playerId);
        if (opponent != null && controller.chooseUse(Outcome.PutCreatureInPlay,"String_Node_Str" + sourceObject.getIdName() + "String_Node_Str"+ opponent.getName()+ "String_Node_Str",source,game)) {
          PutTokenOntoBattlefieldCopyTargetEffect effect=new PutTokenOntoBattlefieldCopyTargetEffect(controller.getId(),null,false,1,true,true,playerId);
          effect.setTargetPointer(new FixedTarget(sourceObject,game));
          effect.apply(game,source);
          tokens.addAll(effect.getAddedPermanent());
        }
      }
    }
    if (!tokens.isEmpty()) {
