Error: "The current and new HumanoidDescription have common assets in different properties"

#1

I have a script that randomly picks clothes, pants, faces, and hats for a character, however it keeps randomly giving me this error. It usually works, but it just breaks and shows this error like 10% of the time for some reason. I looked at every single ID and I dont see any duplicates.
Here is my code:

local policeclothing = {}

local Workspace = game:GetService("Workspace")

local Catalog = {
	shirts = {
		169452027

	},
	pants = {
		2430769797
	},
	faces = {
		141728790,
		7074729,
		9250660,
		7076076,
		7131886,
		66330265,
		823012694,
		150182378,

		9250654,
		7074661,
		14861743,
		110288809 --beard
	},
	hair = {
		32278814,
		13477818,
		3814450142,
		417457139,
		2606178351,

		6467597842,
		11452955059
	}
}

local function RandomizeAppearance(npc)
	-- Get random ids
	local randomShirtId = Catalog.shirts[math.random(1, #Catalog.shirts)]
	local randomPantsId = Catalog.pants[math.random(1, #Catalog.pants)]
	local randomFaceId = Catalog.faces[math.random(1, #Catalog.faces)]
	local randomHairId = Catalog.hair[math.random(1, #Catalog.hair)]

	local skinColor = Color3.fromRGB(204, 142, 105)

	local humanoidDescription = Instance.new("HumanoidDescription")

	-- Apply premade skin color
	humanoidDescription.HeadColor = skinColor
	humanoidDescription.LeftArmColor = skinColor
	humanoidDescription.RightArmColor = skinColor
	humanoidDescription.LeftLegColor = skinColor
	humanoidDescription.RightLegColor = skinColor
	humanoidDescription.TorsoColor = skinColor

	-- Apply random clothing and a face
	humanoidDescription.Shirt = randomShirtId
	humanoidDescription.Pants = randomPantsId
	humanoidDescription.Face = randomFaceId
	humanoidDescription.HatAccessory = randomHairId

	-- Apply the appearance to the humanoid
	npc:WaitForChild("Humanoid"):ApplyDescription(humanoidDescription)

	-- Discard the instance as we will longer need it
	humanoidDescription:Destroy()
end

function policeclothing.pickRandom(char)
	RandomizeAppearance(char)
end

return policeclothing

Thanks in advance.

I’ve stress tested your script and I am unable to get the same results.
I’ve been running it in a while task.wait() do loop for a few minutes and it has yet to error.

I believe you’re experiencing this error as a result of a conflict between this script and an external script – or there is something in the character model that is interfering.
