Can you explain what happened to my tools?

Well I tried to spawn with the tools from the script and it helped but when I spawned the tools were selected while I didn' t select the tools and I can't use them anymore. I think it bugged after the latest ROBLOX update. Here is the script, can you please tell me what I have to fix?

adminlist = {"CenteringParty"}--Put the names of the people you want to get the tools in here

tools = {}
for a,b in ipairs(game.Lighting.Deidara:GetChildren()) do
if b.className == "Tool" or b.className == "HopperBin" then
table.insert(tools,b:clone())
end end 
game.Players.ChildAdded:connect(function(guy)
if guy.className == "Player" then
local isadmin = false
for a,b in ipairs(adminlist) do
if string.lower(b) == string.lower(guy.Name) then
isadmin = true
end end
if isadmin == false then return end
guy.Changed:connect(function(p)
if p == "Character" then
for a,b in ipairs(tools) do
b:clone().Parent = guy.Backpack
end end end)
end end)
