Why is the CFrame of my part not tweening?

I’ve been trying to tween the CFrame of this part that I have welded onto the players HumanoidRootPart. I’m not getting any results, not a single error. It just doesn’t move.

	methods["Soul Siphon"] = function()
		local char = player.Character
		local root = char.HumanoidRootPart
		local animator = char.Humanoid.Animator
		local goingon = true
		local timeer = 3
		local distance = 25
		local waittime = 0.01
		
		local Animation = animator:LoadAnimation(NecromancyAnims:FindFirstChild("SiphonAnimation"))
		Animation:Play()
		
		local tweenINFO = TweenInfo.new(
			1,
			Enum.EasingStyle.Linear,
			Enum.EasingDirection.In,
			0,
			false,
			0
		)
		
		local cloneSiphon = NecromancyModels.Siphon:Clone()
		cloneSiphon.CFrame = root.CFrame*CFrame.new(0,1,-3)
		cloneSiphon.Parent = char
		
		local weldCon = Instance.new("WeldConstraint")
		weldCon.Part0 = root
		weldCon.Part1 = cloneSiphon
		weldCon.Parent = cloneSiphon
		
		for i,living in pairs(workspace.LivingThings:GetChildren()) do -- this is so anything in the folder can get attacked (including actual players)
			living.Archivable = true
		end
		
		wait(1)
		
		Animation:AdjustSpeed(0)

			if particles:IsA("ParticleEmitter") then
				if particles.Name == "Charge" then

I don’t think you can forcefully move CFrame when the part is welded by a Weld or WeldConstraint.
Try using an actual Weld, and tween the Weld’s C0 or C1 property instead.

-- this function welds two parts in place.
local function WeldTwoParts(part0, part1)
    local Weld = Instance.new("Weld")
    Weld.Name = part0.Name .. "_" .. part1.Name
    Weld.Part0 = part0
    Weld.Part1 = part1
    Weld.C0 = part0.CFrame:ToObjectSpace(part1.CFrame)
    Weld.Parent = part1
    return Weld
end

-- assume this is the TweenService and it's TweenInfo you're going to use
local TweenService
local tween_info

-- assume this is a HumanoidRootPart
local RootPart

-- assume this is the part you're trying to move
local Part

-- welding the two parts
Part.CFrame = RootPart.CFrame
local Weld = WeldTwoParts(RootPart, Part)

-- getting the positions
local CurrentCFrame = Weld.C0
local TargetCFrame = CurrentCFrame * CFrame.new(0, 2.5, 0)

-- animation
TweenService:Create(Weld, tween_info, {
    C0 = TargetCFrame
}):Play()

Thanks a lot man! Really appreciate the help. Finally I can continue.
