    • the refering npc is string lenght, so either u edited something badly in html or the size is too big to handle from the client, and propably yan made some customizations to accept bigger size? if also the path is wrong that should be a problem aswell
    • Adapted YanBuffer and everything work fine until i try to talk to the npc. (no errors when building) i get the following: \game\data\scripts\custom\Buffer\Buffer.java java.lang.NullPointerException: Cannot invoke "String.length()" because "html" is null at org.l2jmobius.gameserver.network.serverpackets.AbstractHtmlPacket.setHtml(AbstractHtmlPacket.java:77) at org.l2jmobius.gameserver.network.serverpackets.AbstractHtmlPacket.<init>(AbstractHtmlPacket.java:67) at org.l2jmobius.gameserver.network.serverpackets.NpcHtmlMessage.<init>(NpcHtmlMessage.java:53) at custom.Buffer.Buffer.showAdvancedHtml(Buffer.java:279) at custom.Buffer.Buffer.htmlShowMain(Buffer.java:289) at custom.Buffer.Buffer.executeHtmlCommand(Buffer.java:366) at custom.Buffer.Buffer.executeCommand(Buffer.java:840) at custom.Buffer.Buffer.onFirstTalk(Buffer.java:126) at org.l2jmobius.gameserver.model.quest.Quest.notifyFirstTalk(Quest.java:720) at org.l2jmobius.gameserver.model.quest.Quest.lambda$addFirstTalkId$0(Quest.java:1826) at org.l2jmobius.gameserver.model.events.listeners.ConsumerEventListener.executeEvent(ConsumerEventListener.java:44) at org.l2jmobius.gameserver.model.events.EventDispatcher.notifyToListeners(EventDispatcher.java:289) at org.l2jmobius.gameserver.model.events.EventDispatcher.notifyEventToSingleContainer(EventDispatcher.java:182) at org.l2jmobius.gameserver.model.events.EventDispatcher.lambda$notifyEventAsync$0(EventDispatcher.java:144) at org.l2jmobius.commons.threads.RunnableWrapper.run(RunnableWrapper.java:35) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:833)   and here is the actual code: /* * This file is part of YANModPack: https://github.com/HorridoJoho/YANModPack * Copyright (C) 2015 Christian Buck * * This program is free software: you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation, either version 3 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It is:  \scripts\custom\Buffer\data\htmlpc\main.html  and it should be    \scripts\custom\Buffer\data\html\npc\main.html    Thanks.
