When I clone a character, why does it fall apart?

I'm working on replays for a game, and whenever I clone the character, it just falls apart. Every part in the character is constantly being tweened which confuses me with why none of the parts move

Code:

-- The portion that records the CFrames for the replays to run off of
rec = game:GetService("RunService").RenderStepped:Connect(function()
    for i, v in pairs(game.Players:GetPlayers()) do
        if v.Character then
            if rep[v.Name] == nil then
                rep[v.Name] = {}
            end
            for c, d in pairs(v.Character:GetDescendants()) do          
                if d:IsA("BasePart") then
                    rep[v.Name][d.Name] = {}
                    rep[v.Name][d.Name][tick()] = d.CFrame
