Motor6d's not properly welding parts

I’m working with animations in a game, and some of these animations require a custom rig and some don’t. Mind you the custom rig literally only has 2 parts different so it doesn’t warrant me changing the default rig, as its only needed sometimes. When the player loads I have it trying to set these custom parts into the players rig, and use motor6d’s to do so. That currently looks like this:

game.Players.PlayerAdded:Connect(function(addedPlayer)
	addedPlayer.CharacterAdded:Connect(function(addedCharacter)
		local laPart = game.ReplicatedStorage.gameAssets.LA:Clone()
		local raPart = game.ReplicatedStorage.gameAssets.RA:Clone()
		laPart.CFrame = addedCharacter.LeftHand.CFrame * CFrame.new(0, -3, 0)
		raPart.CFrame = addedCharacter.RightHand.CFrame * CFrame.new(0, -3, 0)
		local lamotor6 = Instance.new("Motor6D")
		lamotor6.Name = "LA"
		lamotor6.Part0 = addedCharacter.LeftHand
		lamotor6.Part1 = laPart
		lamotor6.Enabled = true
		lamotor6.Parent = addedCharacter.LeftHand
		local ramotor6 = Instance.new("Motor6D")
		ramotor6.Name = "RA"
		ramotor6.Part0 = addedCharacter.RightHand
		ramotor6.Part1 = raPart
		ramotor6.Enabled = true
		ramotor6.Parent = addedCharacter.RightHand
		laPart.Parent = addedCharacter
		raPart.Parent = addedCharacter
	end)
end)

On top of this, I decided that due to the unpredictability I would do a check when players get on a base to readd it. That also does not work as you can see from this:

local batterRitual
local batterStance
local batterDebounce = false
workspace.stadiumTemplate.Infield.Bases["Home Plate"].Center.Touched:Connect(function(touch)
	if not batterDebounce then
		batterDebounce = true
		if game.ReplicatedStorage.gameData.positionData.batterPlayer.Value == nil then
			if touch.Parent:FindFirstChild("Humanoid") then
				local player = game.Players:GetPlayerFromCharacter(touch.Parent)
				if player and player.Character then
					batterRitual = player.Character.Humanoid:LoadAnimation(createAnimation("rbxassetid://5058012828", player))
					batterStance = player.Character.Humanoid:LoadAnimation(createAnimation("rbxassetid://5058022763", player))
					batterStance.Looped = true
					game.ReplicatedStorage.gameData.positionData.batterPlayer.Value = player
					player.Character.Humanoid.WalkSpeed = 0
					player.Character.Humanoid.JumpPower = 0
					wait(.1)
					if player.Character:FindFirstChild("LA") and not player.Character:FindFirstChild("RA") then
-- This bit does not like working
						local laPart = game.ReplicatedStorage.gameAssets.LA:Clone()
						local raPart = game.ReplicatedStorage.gameAssets.RA:Clone()
						laPart.CFrame = player.Character.LeftHand.CFrame * CFrame.new(0, -3, 0)
						raPart.CFrame = player.Character.RightHand.CFrame * CFrame.new(0, -3, 0)
						local lamotor6 = Instance.new("Motor6D")
						lamotor6.Name = "LA"
						lamotor6.Part0 = player.Character.LeftHand
						lamotor6.Part1 = laPart
						lamotor6.Enabled = true
						lamotor6.Parent = player.Character.LeftHand
						local ramotor6 = Instance.new("Motor6D")
						ramotor6.Name = "RA"
						ramotor6.Part0 = player.Character.RightHand
						ramotor6.Part1 = raPart
						ramotor6.Enabled = true
						ramotor6.Parent = player.Character.RightHand
						laPart.Parent = player.Character
						raPart.Parent = player.Character
					end
					if game.ReplicatedStorage.playerData[player.UserId].batHand.Value == "Right" then
						local batClone = game.ReplicatedStorage.gameAssets.Bat:Clone()
						batClone.Parent = player.Character
						batClone.CFrame = player.Character.LA.CFrame
						player.Character.LA.Bat.Part1 = batClone
						player.Character.HumanoidRootPart.CFrame = workspace.stadiumTemplate.Infield.Bases["Home Plate"].Center.CFrame * CFrame.new(-5, 4, 0) * CFrame.Angles(0, math.rad(-90), 0)
					else
						local batClone = game.ReplicatedStorage.gameAssets.Bat:Clone()
						batClone.Parent = player.Character
						batClone.CFrame = player.Character.RA.CFrame
						player.Character.RA.Bat.Part1 = batClone
						player.Character.HumanoidRootPart.CFrame = workspace.stadiumTemplate.Infield.Bases["Home Plate"].Center.CFrame * CFrame.new(5, 4, 0) * CFrame.Angles(0, math.rad(90), 0)
					end
					wait(.4)
					player.Character.HumanoidRootPart.Anchored = true
					batterRitual.Stopped:Connect(function()
						batterStance:Play()
					end)
					batterRitual:Play()
				end
			end
		end
	end
end)

What might I be doing to cause the Motor6d’s to disappear with my parts. The code itself isn’t erroring unless the custom rig bits held together via motor6d’s aren’t there. However this issue only occurs sometimes and I can’t live with this unpredictability.

Any help would be appreciated!

Motor6Ds dont conserve the position or cframe of the object, you have to manually set it. I believe you can use object space to set it but otherwise I haven’t done this much.

My issue here isn’t that it is not conserving the position or cframe. When the Motor6d works and keeps the LA and RA parts attached to the rig, the positioning is perfect. The problem is that sometimes the motor6d just doesn’t work. I googled how roblox rigs are held together and apparently it is with motor6d’s from what I read. I imagined adding this part with a Motor6d should work as well.

I edited the code a bit. Still no results unfortunately.

game.Players.PlayerAdded:Connect(function(addedPlayer)

	addedPlayer.CharacterAdded:Connect(function(addedCharacter)
		wait(10)
		local laPart = game.ReplicatedStorage.gameAssets.LA:Clone()
		local raPart = game.ReplicatedStorage.gameAssets.RA:Clone()
		laPart.CFrame = addedCharacter.LeftHand.CFrame * CFrame.new(0, -3, 0)
		raPart.CFrame = addedCharacter.RightHand.CFrame * CFrame.new(0, -3, 0)
		local lamotor6 = Instance.new("Motor6D")
		lamotor6.Name = "LA"
		lamotor6.Enabled = true
		local ramotor6 = Instance.new("Motor6D")
		ramotor6.Name = "RA"
		ramotor6.Enabled = true
		laPart.Parent = addedCharacter
		raPart.Parent = addedCharacter
		ramotor6.Parent = addedCharacter.RightHand
		lamotor6.Parent = laPart
		lamotor6.Part0 = addedCharacter.LeftHand
		lamotor6.Part1 = laPart
		ramotor6.Part0 = raPart
		ramotor6.Part1 = raPart
		laPart.Anchored = false
		raPart.Anchored = false
	end)
end)

Still no results. Any assistance would be appreciated.

Problem Solved. The rig was made wrong so that the motor6d was not in the proper part.
