consegui resolver, o bug estava no modules na pasta data/npc/lib/npcsystem/ e substitua o arquivo modules.lua pelo seguinte codigo:

if(Modules == nil) then
    -- Constants used to separate buying from selling.
    SHOPMODULE_SELL_ITEM = 1
    SHOPMODULE_BUY_ITEM = 2
    SHOPMODULE_BUY_ITEM_CONTAINER = 3

    -- Constants used for shop mode. Notice: addBuyableItemContainer is working on all modes
    SHOPMODULE_MODE_TALK = 1 -- Old system used before Tibia 8.2: sell/buy item name
    SHOPMODULE_MODE_TRADE = 2 -- Trade window system introduced in Tibia 8.2
    SHOPMODULE_MODE_BOTH = 3 -- Both working at one time

    -- Used in shop mode
    SHOPMODULE_MODE = SHOPMODULE_MODE_BOTH

    -- Constants used for outfit giving mode
    OUTFITMODULE_FUNCTION_OLD = doPlayerAddOutfit -- Gives outfit through look type
    OUTFITMODULE_FUNCTION_NEW = doPlayerAddOutfitId -- Gives outfit through outfit id

    -- Used in outfit module
    OUTFITMODULE_FUNCTION = OUTFITMODULE_FUNCTION_NEW
    if(OUTFITMODULE_FUNCTION == nil) then
        OUTFITMODULE_FUNCTION = OUTFITMODULE_FUNCTION_OLD
    end

    -- These callback function must be called with parameters.npcHandler = npcHandler in the parameters table or they will not work correctly.
