Seductive_Whisper quest onKill

[Vampire]

I am having problems with this quest. Console keeps spamming me with this:

com.l2jserver.gameserver.model.quest.Quest showError WARNING: game\data\scripts\quests\QuestMasterHandler.java java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.LinkedList.checkElementIndex(Unknown Source) at java.util.LinkedList.get(Unknown Source) at quests.Q00663_SeductiveWhispers.Q00663_SeductiveWhispers.onKill(Q00663_SeductiveWhispers.java:753) at com.l2jserver.gameserver.model.quest.Quest.notifyKill(Quest.java:591) at com.l2jserver.gameserver.model.quest.Quest.lambda$addKillId$15(Quest.java:1941) at com.l2jserver.gameserver.model.events.listeners.ConsumerEventListener.executeEvent(ConsumerEventListener.java:46) at com.l2jserver.gameserver.model.events.EventDispatcher.notifyToListeners(EventDispatcher.java:242) at com.l2jserver.gameserver.model.events.EventDispatcher.notifyEventImpl(EventDispatcher.java:216) at com.l2jserver.gameserver.model.events.EventDispatcher.notifyEvent(EventDispatcher.java:85) at com.l2jserver.gameserver.model.events.EventDispatcher.lambda$notifyEventAsyncDelayed$1(EventDispatcher.java:135) at com.l2jserver.gameserver.ThreadPoolManager$RunnableWrapper.run(ThreadPoolManager.java:89) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(Unknown Source) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

any idea what should it be?

Can you explain me when this error appears?

[Vampire]

Some of my players told me that it happens when they do some quest for clan. This is random. I am not sure.... When they kill those mobs that are related to this quest, that happens. And i got full console of this error repeating.

I fixed this problem guys, it is the line 753 You have to put this on the line 753:

final L2PcInstance rewardedPlayer = (players.size() == 0) ? null : players.get(getRandom(players.size()));

Edit line 753 = final L2PcInstance rewardedPlayer = (players.size() == 0) ? null : players.get(getRandom(players.size()));
