Estou com um problema no go/backd o MatheusMkalo

Ele buga a pokebola as vezes e fica com HP=XXX A MAXH=-1

Com o maxhealth -1 a npc heal nao consegue healar a pokebola. Queria que alguem fizesse uma table nesse script para ao inves de pegar o hp da description da pokebola pegasse na table.

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

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

function creatureSayCallback(cid, type, msg)

   if(not npcHandler:isFocused(cid)) then
       return false
   end

   if msgcontains(msg, 'heal') then
       if #getCreatureSummons(cid) >= 1 then
           return selfSay('Voce precisa botar seus pokemons dentro da pokebola.', cid)
       end
