here is bugged function:

local function getRequiredThings(cid)
local itemsleft = {}
local check = {}

for t = 1, 6 do
	check[t] = ""
	for i,x in pairs(cfg.quests[t].itemsReq) do
		local item = getPlayerItemCount(cid, i)
		if (item < x.amount) then
			table.insert(itemsleft[t], x.amount - item.. "x "..getItemNameById(i))
		end
	end
	check[t] = #itemsleft[t] > 0 and "Items: "..table.concat(itemsleft[t], ", ") or "" -- bugged (line 224)
end
return check[1], check[2], check[3], check[4], check[5], check[6]
end

bugged line:

		check[t] = #itemsleft[t] > 0 and "Items: "..table.concat(itemsleft[t], ", ") or ""

help :S

Put right after, or before

check[t] = ""

this:

itemsleft[t] = {}
