you can send the multisell to the player with this method if I'm right:
public final void separateAndSend(int listId, L2PcInstance player, L2Npc npc, boolean inventoryOnly)
in Multisell.java. at least the Multisell bypasshandler use this method
so in your case you have to call this:
else if (_command.startsWith("aio_Agathions"))
{
if (Config.ENABLE_Aio_Agathions)
{
MultiSell.getInstance().separateAndSend(90042, activeChar, (L2Npc) target, false);
}
{
