HumanoidDescription won't work anymore. Please help?

Hi, I made this script to load the character with a set avatar and it worked for a while but now it won't for some reason. There's nothing in the console either.

game.Players.CharacterAutoLoads = false

local function onPlayerAdded(player)
	local humanoidDescription = Instance.new("HumanoidDescription")
	humanoidDescription.HatAccessory = "1915075589"
	humanoidDescription.Shirt = "249291407"
	humanoidDescription.Pants = "249291430"
	player:LoadCharacterWithHumanoidDescription(humanoidDescription)
end


game.Players.PlayerAdded:Connect(onPlayerAdded)

Please help.
