Physics ownership over NPC Humanoids stops them from working properly!

I have found a bug in my game which seems to be caused by changes in physics ownership. Basically I am creating an NPC on the server and then telling it to follow a path of Vector3s. This works fine to start with but as soon as a player comes near enough that the physics ownership transfers from the server to the client, the humanoid stops walking. If the player moves away and the server regains ownership, the humanoid continues walking again.

Here is a video which demonstrates this using the studio physics option “AreOwnersShown”:

And here is the code which makes the NPC and then tells it to walk around:

function class:makeCharacterJoints(model)
	local joints = {}
	
	joints.root = weld("RootJoint", model.HumanoidRootPart, model.Torso)
	joints.neck = weld("Neck", model.Torso, model.Head)
	joints.leftHip = weld("Left Hip", model.Torso, model["Left Leg"])
	joints.rightHip = weld("Right Hip", model.Torso, model["Right Leg"])
	joints.leftShoulder = weld("Left Shoulder", model.Torso, model["Left Arm"])
	joints.rightShoulder = weld("Right Shoulder", model.Torso, model["Right Arm"])
	joints.eyes = weld("Eyes", model.Head, model.Eyes, nil, model.Eyes.CFrame:toObjectSpace(model.Head.CFrame))
	
	return joints
end

function class:createNpc(name, walkSpeed)
	local npc = {}
	npc.character = assets.Character:Clone()
	npc.character.Name = name
	npc.humanoid = npc.character.Humanoid
	
	npc.joints = self:makeCharacterJoints(npc.character)
	
	npc.humanoid.WalkSpeed = walkSpeed or 12
	
	self:changeEyeColor(npc.character, clothes.eyeColor)
	self:changeSkinColor(npc.character, clothes.skinColor)
	
	local function reverseTable(init)
		local reversed = {}
		for i, v in next, init do
			reversed[#init - i + 1] = v
		end
		return reversed
	end
	
	function npc:startPath(path, loopMode)
		for i, node in next, path do
			if node.dur then
				wait(node.dur)
			end
			
			local torsoPos = self.character.Torso.Position
			repeat
				torsoPos = self.character.Torso.Position
				self.humanoid:Move((Vector3.new(node.pos.X, torsoPos.Y, node.pos.Z) - torsoPos).unit)
				wait(.1)
			until (Vector3.new(node.pos.X, torsoPos.Y, node.pos.Z) - torsoPos).magnitude <= 5
		end
		
		if loopMode == "Loop" then
			npc:startPath(path, loopMode)
		elseif loopMode == "PingPong" then
			npc:startPath(reverseTable(path), loopMode)
		end
	end
	
	function npc:spawn(pos)
		self.character.Parent = workspace
		self.character:MoveTo(pos)
		game.ReplicatedStorage.Events.Animate:FireAllClients("Play", npc.character, "Idle", clock.Value)
	end
	
	npc.humanoid.Running:connect(function(speed)
		if speed > 0 then
			game.ReplicatedStorage.Events.Animate:FireAllClients("Crossfade", npc.character, "Walk", clock.Value, 0.2)
		else
			game.ReplicatedStorage.Events.Animate:FireAllClients("Crossfade", npc.character, "Idle", clock.Value, 0.2)
		end
	end)
	
	return npc
end

....

local path = {
	{
		pos = Vector3.new(10, 3, 10)
	},
	{
		pos = Vector3.new(30, 3, 10)
	},
	{
		pos = Vector3.new(30, 3, 30)
	},
	{
		pos = Vector3.new(10, 3, 30)
	},
}

local bob = CharacterHandler:createNpc("Bob")
bob:spawn(path[1].pos)
bob:startPath(path, "Loop")

Lastly, here is a repro place for the mods (contains some game assets, not showing to general public)

EDIT: Just found out this was already reported here but this deserves a bump anyways!
