Im not sure why this is happening? Any help is appreciated. Here is the welding Script.

	player.Character.HumanoidRootPart.Anchored = true
	local newArmor = player.Backpack:FindFirstChild(armorName):Clone()
	newArmor.Anchored = true
	newArmor.Parent = player.Character
	local weld = Instance.new("Weld",newArmor)
	weld.Part0 = newArmor
	weld.Part1 = player.Character.HumanoidRootPart
	newArmor.Anchored = false
	player.Character.HumanoidRootPart.Anchored = false

Sorry For Wasting Everybodys time :/.

I Just figured it out! I will leave it up just incase someone else runs into problem :).

What you have to do is not weld to HumanoidRootPart but rather UpperTorso!!
