Datastore not saving table?

So I have be trying to make this datastore save this table now for ages and it doesn't seem to work, here is everything you will need:

DataStore Module (It is being called)

local module = {}
    local datastore = game:GetService("DataStoreService"):GetDataStore("Data-3F61CC598CD962DFFA1B88FDF2C79")

    local stats = {
        FirstPlay = true;
        Money = 100;
        Level = 0;
        Prestige = 0;
        guns = {"M16"};
        attachments = {};
        skins = {};
    }

    game.Players.PlayerAdded:Connect(function(player)
        local savedStats = datastore:GetAsync(player.userId.."-Stats")
        print(savedStats)
        if savedStats ~= nil then
            stats = savedStats
        end

        datastore:SetAsync(player.userId.."-Stats",stats)

        local sf = Instance.new("Folder",player)
        sf.Name = "Stats"

        local F = Instance.new("BoolValue",sf)
        F.Name = "FirstPlay"
        F.Value = stats.FirstPlay

        local M = Instance.new("IntValue",sf)
        M.Name = "Money"
        M.Value = stats.Money

        local L = Instance.new("IntValue",sf)
        L.Name = "Level"
        L.Value = stats.Level

        local P = Instance.new("IntValue",sf)
        P.Name = "Prestige"
        P.Value = stats.Prestige

        local G = Instance.new("Folder",sf)
        G.Name = "Guns"
        for i = 1, #stats.guns do
            local GG = Instance.new("StringValue",G)
            GG.Name = "Gun"
            GG.Value = stats.guns[i]            
        end

        local A = Instance.new("Folder",sf)
        A.Name = "Attachments"
        for i = 1, #stats.attachments do
            local AA = Instance.new("StringValue",A)
            AA.Name = "Attachment"
            AA.Value = stats.attachments[i]         
        end

        local S = Instance.new("Folder",sf)
        S.Name = "Skins"
        for i = 1, #stats.skins do
            local SS = Instance.new("StringValue",A)
            SS.Name = "Skin"
            SS.Value = stats.skins[i][1]
            local SG = Instance.new("StringValue",SS)
            SG.Name = "For"
            SG.Value = stats.skins[i][2]        
        end
    end)

    game.Players.PlayerRemoving:Connect(function(player)
        local pStats = player:WaitForChild("Stats")
        local saveGuns = {}
        for i = 1, #pStats.Guns:GetChildren() do
            table.insert(saveGuns, pStats.Guns:GetChildren()[i].Value)
        end
        local saveAttachments = {}
        for i = 1, #pStats.Attachments:GetChildren() do
            table.insert(saveAttachments, pStats.Attachments:GetChildren()[i].Value)
        end
        local saveSkins = {}
        for i = 1, #pStats.Attachments:GetChildren() do
            local skin = {pStats.Attachments:GetChildren()[i].Value,pStats.Attachments:GetChildren()[i].For.Value}
            table.insert(saveSkins, skin)
        end

        print(pStats.FirstPlay.Value,pStats.Money.Value,pStats.Level.Value,pStats.Prestige.Value,saveGuns,saveAttachments,saveSkins)

        stats.FirstPlay = pStats.FirstPlay.Value
        print(stats.FirstPlay)
        stats.Money = pStats.Money.Value
        stats.Level = pStats.Level.Value
        stats.Prestige = pStats.Prestige.Value
        stats.guns = saveGuns
        stats.attachments = saveAttachments
        stats.skins = saveSkins

        print(#stats)

        datastore:SetAsync(player.userId.."-Stats",stats)
    end)

return module

Output:

table: 3DA4E16C
false 100 0 0 table: 1FAB5CB4 table: 1FAB5BC4 table: 1FAB5C54
true
0
