My dataStore loads random data?

Some Players in my game have complained about having their Data being changed on entering a different server,some aren't affected and some say that it happens when I use the shutdown all servers button . Apparently the intValues that the datastores are saving are being replaced by random numbers?

I can't seem to find anything wrong with the scripts. I'm hoping someone else can review my script and reassure this should work as intended.

local saveAs = "HS"

local dataStore = game:GetService("DataStoreService"):GetDataStore(saveAs)
local Players = game:GetService("Players")

Players.PlayerAdded:connect(function(player)
    local stats = player:WaitForChild("Hstats")
    local data = dataStore:GetAsync(player.UserId)
    if data then
        for name,value in next, data do
            stats[name].Value = value 
        end
    end
end)

Players.PlayerRemoving:connect(function(player)
    local stats = player:FindFirstChild("Hstat")
    if stats then
        local data = {}
        for _,stat in ipairs(stats:GetChildren()) do
            data[stat.Name] = stat.Value
        end
        dataStore:SetAsync(player.UserId,data)
    end
end)

while wait(61) do
    for _, player in pairs(game.Players:GetChildren()) do
local stats = player:FindFirstChild("Hstat")
    if stats then
        local data = {}
        for _,stat in ipairs(stats:GetChildren()) do
            data[stat.Name] = stat.Value
        end
        dataStore:SetAsync(player.UserId,data)
    end
end
end 



game.OnClose = function()
    wait(10)
end
