Hello everyone, everything good?

I think it's the weirdest problem I've ever seen happen on a server, I have no idea what it causes. Sometimes on my server, when I talk to an NPC it responds as if it were another, example: my NPC Djin sometimes responds as if it were my NPC Task, it's very strange, the console doesn't give any error. Then I say "bye" and say "hi" again and he responds normally, has anyone been through this?

It only makes sense to me if it's something in the NPC lib, so I'll post npchandler.lua, follow:

Lua:
-- Advanced NPC System (Created by Jiddo),
-- Modified by TheForgottenServer Team,
-- Modified by The OTX Server Team.

if(NpcHandler == nil) then
    -- Constant talkdelay behaviors.
    TALKDELAY_NONE = 0 -- No talkdelay. Npc will reply immedeatly.
    TALKDELAY_ONTHINK = 1 -- Talkdelay handled through the onThink callback function. (Default)
    TALKDELAY_EVENT = 2 -- Not yet implemented

    -- Currently applied talkdelay behavior. TALKDELAY_ONTHINK is default.
    NPCHANDLER_TALKDELAY = TALKDELAY_ONTHINK

    -- Constant conversation behaviors.
    CONVERSATION_DEFAULT = 0 -- Conversation through default window, like it was before 8.2 update.
    CONVERSATION_PRIVATE = 1 -- Conversation through NPCs chat window, as of 8.2 update. (Default)
        --Small Note: Private conversations also means the NPC will use multi-focus system.

    -- Currently applied conversation behavior. CONVERSATION_PRIVATE is default.
    NPCHANDLER_CONVBEHAVIOR = CONVERSATION_DEFAULT

    -- Constant indexes for defining default messages.
    MESSAGE_GREET             = 1 -- When the player greets the npc.
    MESSAGE_FAREWELL         = 2 -- When the player unGreets the npc.
    MESSAGE_BUY             = 3 -- When the npc asks the player if he wants to buy something.

    MESSAGE_SOLD            = 8 -- When the player sold something through the shop window.
    MESSAGE_MISSINGMONEY        = 9 -- When the player does not have enough money.

I would try removing this line too
Lua:
npcHandler:setCallback(CALLBACK_GREET, greet)
still dont, if i say "hi" to a busy npc and goes to a free npc, second npc put me in a queue, even with nobody talking to him.

@Oskar1121 told me once: "I do recommend to have a look into addEvent functions. " and "Change self.focuses from integer to table".

1 year without solving lua? Lol

Show us your FocusModule:init function (it seems like it's not even imported, is it?)
Here, there is on modules.lua (on lib folder of NPCs)

Lua:
    -- Inits the module and associates handler to it.
    function FocusModule:init(handler)
        self.npcHandler = handler
        for i, word in pairs(FOCUS_GREETWORDS) do
            local obj = {}
            table.insert(obj, word)

            obj.callback = FOCUS_GREETWORDS.callback or FocusModule.messageMatcher
            handler.keywordHandler:addKeyword(obj, FocusModule.onGreet, {module = self})
        end

        for i, word in pairs(FOCUS_FAREWELLWORDS) do
            local obj = {}
            table.insert(obj, word)

            obj.callback = FOCUS_FAREWELLWORDS.callback or FocusModule.messageMatcher
            handler.keywordHandler:addKeyword(obj, FocusModule.onFarewell, {module = self})
        end
    end
