Problem while loading the objects of a placement system where is the problem?

I have created a placement system and this worked without any problems, however, I tried when loading the Playerbase to add a standard rotatio which makes it possible to change the orientation of all the objects of a player base at once. However, I came across a problem here. When loading the rotated player base sometimes all the objects move by 0.5.

This is my loading function:

function loadPlayerData(player, dataTable, Base)

    if dataTable ~= nil then

        for _, object in pairs(dataTable["PlacedObjects"]) do

            if object["Name"] ~= "Anchor" then

                local Model = game.ReplicatedStorage.PlaceableObjects:FindFirstChild(object["Name"]):WaitForChild("PlacedModel"):Clone()
                Model.Name = object["Name"]

                Model.Parent = Base.PlacedObjects
                Model:SetPrimaryPartCFrame(Base.Grid.CFrame + Vector3.new(object["XPos"], object["YPos"], object["ZPos"]))

                Model.Rotation.Value = object["Rotation"] + game.Workspace:WaitForChild(player:WaitForChild("PlayerSystem"):WaitForChild("Values").PlayerBase.Value).Settings.BaseRotation.Value
                Model:SetPrimaryPartCFrame(Model:GetPrimaryPartCFrame() * CFrame.Angles(0, math.rad(object["Rotation"]),0))

            end

        end

        local PlacedObjectsModel = game.Workspace:WaitForChild(player.PlayerSystem.Values.PlayerBase.Value).PlacedObjects

PlacedObjectsModel:SetPrimaryPartCFrame(PlacedObjectsModel:GetPrimaryPartCFrame() * CFrame.Angles(0, math.rad(Base.Settings.BaseRotation.Value) ,0))

    end
end

And this is my save function:

function generateDataTable(player, Base)

    local PlacedObjects = {}

    local TempObject = Base.PlacedObjects:Clone()
    local cframe = TempObject.PrimaryPart.CFrame
    TempObject:SetPrimaryPartCFrame(cframe * CFrame.Angles(0, math.rad( - Base.Settings.BaseRotation.Value), 0))

    for _, object in pairs (TempObject:GetChildren()) do

        if object.Name ~= "Anchor" then

            local vector,axis = object:GetPrimaryPartCFrame():toAxisAngle()
            local pos = object.PrimaryPart.Position - Base.Grid.Position
            table.insert(PlacedObjects, {
                ["Name"] = object.Name,
                ["XPos"] = pos.X,
                ["YPos"] = pos.y, 
                ["ZPos"] = pos.z, 
                ["Rotation"] = object.Rotation.Value - Base.Settings.BaseRotation.Value})

        end

    end


    local dataTable = {
        ["PlacedObjects"] = PlacedObjects

}

    TempObject:Destroy()
    return dataTable

end
