More questions on my script?

In my script I am attempting to make a model with a humanoid in it. The script works, but when I make the player's character the model I made, the character resets soon after the line of code runs.

The script:

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
repeat wait() until player.Character
local char = player.Character

mouse.KeyDown:connect(function(key)
    key = key:lower()
    if key == "v" then
        char.Archivable = true
        local clone = char:Clone()
        local model = Instance.new("Model",game.Workspace)
        local ball = Instance.new("Part",model)
        ball.Name = "Head"
        ball.Size = Vector3.new(5,5,5)
        ball.BrickColor = BrickColor.new("Really blue")
        ball.FormFactor = "Custom"
        ball.Shape = "Ball"
        ball.CanCollide = false
        ball.TopSurface = "Smooth"
        ball.BottomSurface = "Smooth"
        local ball2 = ball:Clone()
        ball2.Name = "Torso"
        ball2.Parent = model
        ball2.Size = Vector3.new(6,6,6)
        ball2.Transparency = 0.3
        ball.Position = char.Torso.Position
        ball2.Position = ball.Position
        ball.Anchored = true
        ball2.Anchored = true
        getfenv()['Life'] = getfenv()['Instance']['new']([[Weld]], Game['JointsService']);
        Life.C1 = ball2.CFrame:toObjectSpace(ball.CFrame);
        Life.Part0 = ball
        Life.Part1 = ball2
        local humanoid = Instance.new("Humanoid")
        humanoid.MaxHealth = 100
        humanoid.Health = 100
        humanoid.Parent = model
		model.Name = player.Name
		player.Character = model
    end
end)

My question: Is there any way to keep the player resetting other than turning off the 'AutoCharacterLoads' property?
