Why are parts that are welded to a tweening part not moving with it?

So I am rewriting one of my old games. While making a model that moves up I stumbled upon an issue. The Welded parts (Weld Constraints) are not moving with the anchored tweening part. The parts that are welded to the tweening part are not anchored. I do not know why the welded parts are not moving with the tweening part. The welded parts that are not anchored are still kinda attached and won’t fall or move. It’s like the welds ignore the tweens and stay where they are.

Here is the model:

This is the code for the tween. I always do them in one line.

TweenService:Create(BobuxPipeScene1Clone.Primary, TweenInfo.new(11.128, Enum.EasingStyle.Sine, Enum.EasingDirection.Out), {Position = Vector3.new(-20, 7, -28)}):Play()

Help would be appreciated!

Try using CFrame instead of position.

TweenService:Create(BobuxPipeScene1Clone.Primary, TweenInfo.new(11.128, Enum.EasingStyle.Sine, Enum.EasingDirection.Out), {Position = Vector3.new(-20, 7, -28)}):Play()

Try using

TweenService:Create(BobuxPipeScene1Clone.Primary, TweenInfo.new(11.128, Enum.EasingStyle.Sine, Enum.EasingDirection.Out), {CFrame = CFrame.new(Vector3.new(-20, 7, -28))}):Play()
