local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid) npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid) npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg) npcHandler:onCreatureSay(cid, type, msg) end
function onThink() npcHandler:onThink() end

local shopWindow = {}

local things = {
     {action = 0, id = 6512, buy = 25, name = "Stamina Doll"},
     {action = 0, id = 5958, buy = 1, name = "Charged Summon Scroll"}
}

local onBuy = function(cid, item, subType, amount, ignoreCap, inBackpacks)
local TradeItem = 2328
doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "You have bought "..shopWindow[item].Price*amount.."")
        if doPlayerRemoveItem(cid, TradeItem, shopWindow[item].Price*amount)  then
         if isItemStackable(item) then
             doPlayerAddItem(cid, item, amount)
         else
             for x = 1, amount do
                 doPlayerAddItem(cid, item, 1)
             end
         end
         doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "You have bought "..amount.."x "..shopWindow[item].Name.." for "..shopWindow[item].Price*amount.." warfare tokens.")
     else
         selfSay("You don't have warfare tokens.", cid)
     end
     return true
end



function creatureSayCallback(cid, type, msg)
     if not npcHandler:isFocused(cid) then
         return false
     end

    if msgcontains(msg, 'rem') then
        doPlayerRemoveItem(cid, 2328, 5)
    end


     if msgcontains(msg, 'trade') then
        if getPlayerGroupId(cid) > 0 then
             for var, item in pairs(things) do
                if item.action == 0 then
                    shopWindow[item.id] = {Price = item.buy, Name = item.name}
                elseif item.action == 1 then
                    shopWindow[item.id] = {Price = item.sell, Name = item.name}
                end
             end
             openShopWindow(cid, things, onBuy,2, onSell)
        else
            npcHandler:say("This shop is only for tutors sorry.")
        end
     end
     return true
end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

I don't really know if is on the engine or client-sided, but nothing that you could fix changing your script.
