Creating a weld is snapping the character's neck..?

[NecroTwist]

I am making a character editor and I am trying to make a button to duplicate a selected hat, but when I do, the accessoryWeld does not carry over and attempting to create a new one ‘snaps’ the characters neck.

Here are some important things to note:

• :Clone()'ing an accessory from the hats already on your characters does work, but not with inserted accessories.
• Welds otherwise work, just not for the duplicated accessory, check following screenshots and try to find a discrepency maybe?
• Also, using studio’s CTRL+D does not make this issue occur, it functions expectedly.

(duplication code)

local function duplicateAsset(player, asset)
	if checkLimit(player.Character) == false then return end
	
	local duplicate = asset:Clone()
	duplicate.Parent = player.Character
	
	local weld = duplicate.Handle:FindFirstChild("AccessoryWeld")
	if not weld then
		weld = Instance.new("Weld")
		weld.Parent = duplicate.Handle
		weld.Part0 = duplicate.Handle
		weld.Part1 = asset.Handle.AccessoryWeld.Part1
		weld.C0 = asset.Handle.AccessoryWeld.C0
		weld.C1 = asset.Handle.AccessoryWeld.C1
		weld.Name = "AccessoryWeld"
	end
	
	UpdateListEvent:FireClient(player)
end

(insertion code – if this helps, also not all code, if more is necessary then ask)

local specialMesh = asset.Handle:FindFirstChildWhichIsA("SpecialMesh")
			
			-- create a mesh part from the specialmesh
			local success, meshPart = pcall(function()
				return AssetService:CreateMeshPartAsync(specialMesh.MeshId, {["CollisionFidelity"] = Enum.CollisionFidelity.Box})
			end)
			
			if success and meshPart then
				-- set original so it creates accessorywelds
				asset.Parent = character
				
				-- create weld and attachment
				local weld = Instance.new("Weld")
				local attachment = Instance.new("Attachment")
				local accessory = Instance.new("Accessory")
				
				accessory.Name = asset.Name
				accessory.Parent = character
				meshPart.Parent = accessory
				meshPart.Name = "Handle"
				
				weld.Parent = meshPart
				weld.Part0 = meshPart
				weld.Part1 = asset.Handle.AccessoryWeld.Part1
				weld.C0 = asset.Handle.AccessoryWeld.C0
				weld.C1 = asset.Handle.AccessoryWeld.C1
				weld.Name = "AccessoryWeld"
				
				attachment.Parent = meshPart
				attachment = asset.Handle:FindFirstChildWhichIsA("Attachment")
				
				meshPart.TextureID = specialMesh.TextureId
				meshPart.CanCollide = false
			end

So… apparently Roblox was creating a weld on the head, for some inexplicable reason. I do not know why it was only doing it with inserted accessories, or whatever, but I have fixed it. I simply deleted the weld Roblox created.

If someone in the future can explain why Roblox does this, it would be much appreciated it.
