Currently running a 9.60 tibia with TFS 2.14.
Anyone know what is causing this problem? It happens with all BANK NPC's.

I searched for a similar error, try this:

Search for this in data/npc/lib/npcsystem/npchandler.lua:

function NpcHandler:say(message, focus, publicize, shallDelay, delay)
                if(type(message) == "table") then
                        return self:doNPCTalkALot(message, delay or 10000, focus)
                end

                if self.eventDelayedSay[focus] then
                        self:cancelNPCTalk(self.eventDelayedSay[focus])
                end

                local shallDelay = not shallDelay and true or shallDelay
                if(NPCHANDLER_TALKDELAY == TALKDELAY_NONE or shallDelay == false) then
                        selfSay(message, focus, publicize and TRUE or FALSE)
                        return
                end

                stopEvent(self.eventSay[focus])
                self.eventSay[focus] = addEvent(function(x) if isPlayer(x[3]) then doCreatureSay(x[1], x[2], TALKTYPE_PRIVATE_NP, false, x[3], getCreaturePosition(x[1])) end end, self.talkDelayTime * 1000, {getNpcCid(), message, focus})
        end

And replace it with:

 function NpcHandler:say(message, focus, publicize, delay)
		if type(message) == 'table' then
			return self:doNPCTalkALot(message, delay or 10000, focus)
		end

		focus = focus or 0
		if self.eventDelayedSay[focus] then
			self:cancelNPCTalk(self.eventDelayedSay[focus])
		end

		stopEvent(self.eventSay[focus])
		self.eventSay[focus] = addEvent(function(x) doCreatureSay(x[1], x[2], x[3] == 0 and TALKTYPE_SAY or TALKTYPE_PRIVATE_NP, false, x[3], getThingPos(x[1])) end, 1000, {getNpcCid(), message, focus})
	end

Testing it now, I also get some errors when starting the server.

[29/11/2012 21:01:06] [Warning - NpcScript::NpcScript] Can not load script: default.lua
[29/11/2012 21:01:06] cannot open default.lua: No such file or directory

I have the default.lua file in my data folder, but migth be in the wrong place? Where is it supposed to be?
