Tool saving script only loaded tools once? [FIXED]

So, I followed a yt tutorial on how to make a tool saving script. The first time I tried loading the tools it worked normally, but the 2nd time I played the game the script broke. Does anybody know how to fix this? Here's the script:

local dss = game:GetService("DataStoreService")
local toolsDS = dss:GetDataStore("ToolsData")

local toolsFolder = game.ServerStorage.ToolsFolder

game.Players.PlayerAdded:Connect(function(plr)

    local toolsSaved = toolsDS:GetAsync(plr.UserId .. "-tools") or {}

    for i, toolSaved in pairs(toolsSaved) do

        if toolsFolder:FindFirstChild(toolSaved) then 

            toolsFolder[toolSaved]:Clone().Parent = plr.Backpack
            toolsFolder[toolSaved]:Clone().Parent = plr.StarterGear 

        end
    end

    plr.CharacterRemoving:Connect(function(char)

        char.Humanoid:UnequipTools()
    end)
end)


game.Players.PlayerRemoving:Connect(function(plr)

    local toolsOwned = {}

    for i, toolInBackpack in pairs(plr.Backpack:GetChildren()) do

        table.insert(toolsOwned, toolInBackpack.Name)
    end

    local success, errormsg = pcall(function()

        toolsDS:SetAsync(plr.UserId .. "-tools", toolsOwned)
    end)
    if errormsg then warn(errormsg) end
end)

game:BindToClose(function()
    local players = game.Players:GetPlayers()
    for i = 1, #players do
        local plr = players[i]

        local toolsOwned = {}

    for i, toolInBackpack in pairs(plr.Backpack:GetChildren()) do

        table.insert(toolsOwned, toolInBackpack.Name)
    end

    local success, errormsg = pcall(function()

        toolsDS:SetAsync(plr.UserId .. "-tools", toolsOwned)
    end)
    if errormsg then warn(errormsg) end

    end
    end)

Also, I would like to address some common questions you may ask: 1. API Services are enabled. 2. I tested it both in studio and in the real game. 3. There are no errors in the output. 4. I can tell the problem is with loading the tools because when I stop the game in the output it says "DataStore request was added to queue. If request queue fills, further requests will be dropped. Try sending fewer requests.Key = 178628425-tools", meaning that it saved properly.

So if anybody could help I would really appreciate it!
