tr1::bad_weak_ptr

Bug Reports Engine Bugs
#1

I wrote this server script for Catalog Heaven which attempts to destroy tools when the handle is destroyed. I just noticed this error in the developer console (occurs rarely):

tr1::bad_weak_ptr
Script 'Players.questionabletello.Backpack.HandleRemovalDetector', Line 11
Stack End

Am I doing something horribly wrong here to cause this error? Here’s the code:

local player = script.Parent.Parent
local character = player.Character
if not character or not character.Parent then
	character = player.CharacterAdded:wait()
end

-- if a tool's handle is removed from the tool, then nuke the tool

character.DescendantRemoving:connect(function(descendant)
	if descendant.Name == "Handle" then
		local tool = descendant.Parent and descendant.Parent:IsA("Tool") and descendant.Parent --> tr1::bad_weak_ptr
		if tool then
			wait(0)
			if not descendant.Parent then
				print("Removing tool without handle")
				pcall(function() tool:Destroy() end)
			end
		end
	end
end)

not sure, probably has something to do with a hack they have somewhere, as a workaround, you could just parent the tool to nil, and let the GC eat it, as it might have something to do with the tool being removed before the handle, and it was unexpected behavior
