script breaks after you die/reset?

game.Players.PlayerAdded:Connect(function(plr)
    plr.CharacterAdded:Connect(function(char)
	repeat wait() until plr.Character:FindFirstChild("Humanoid")
	while wait() do
	if char:FindFirstChild("ForceField") then
				for _,c in pairs(plr.Backpack:GetChildren()) do
				local bp = c:Clone()
				c:Destroy()
				bp.Parent = plr.PlayerGui.tools
				end
				else
				for _,v in pairs(plr.PlayerGui.tools:GetChildren()) do
				local pb = v:Clone()
				v:Destroy()
				pb.Parent = plr.Backpack
				end
		end
	end
	char.Humanoid.Died:connect(function()
				for _,c in pairs(plr.Backpack:GetChildren()) do
				local bbp = c:Clone()
				c:Destroy()
				bbp.Parent = plr.PlayerGui.tools
				end
				end)
end)
end)


--Broken, it spams after u reset.

I made this script, basically what it does is: if you are inside a forcefield, it clones the items from ur inv, puts them in a folder and the deletes the one in ur inventory. if you are outside the forcefield then it puts your items back in ur inv and deletes them from the folder.

The problem is: it works perfectly until you reset/die, once you die and respawn the script starts to spam the items in your inventory like this: https://gyazo.com/59e1b824d31b546f92898e3e789514e2
