Custom Player Model from script that still dies on explosion?

Hi, I am making a game where certain players are "disguised" as pumpkins. I am trying to get it so that upon death from an explosive force that rips the rig apart causing death, they respawn as a pumpkin model. So far I have this code:

local fakeChar = game.ServerStorage.Model -- The character to load
local respawnTime = 1
game:GetService('Players').PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		character:WaitForChild("Humanoid").Died:Connect(function()
			print "die"
			playerAdded(player)
		end)
	end)
end)

function playerAdded(player)
	if player.Character and player.Character.Parent then -- Destroy an already-existing character
		player.Character:Destroy()
	end

	while player.Parent do -- Repeat until they leave the game
		loadChar(player) -- Method waits until they die
		wait(respawnTime)
	end
end

function loadChar(player)
	local char = fakeChar:clone()
	char.Name = player.Name

	local humanoid
	for i, child in pairs(char:GetChildren()) do -- Find the humanoid
		if child.ClassName == "Humanoid" then
			humanoid = child
			break
		end
	end

	if not humanoid then -- If no humanoid was found, make one
		humanoid = Instance.new("Humanoid", char)
	end

	player.Character = char
	char.Parent = game.Workspace
	humanoid.Health = 100
	humanoid.Died:wait() -- Wait until they die
end

This works to some degree. However, once the player's default character model has died, if the pumpkin then explodes again, while the pumpkin model flies away, the player can walk around while the pumpkin model stays where it was (dunno if that makes any sense)

This is the Model referenced in the script: https://i.imgur.com/CbBbIGM.png The "Torso" is simply a mesh of the pumpkin, while the "HumanoidRootPart" is an invisible part.

Does anyone know how I can achieve my desired result? Basically, if I copy the player's starting model and paste it into the Model in serverstorage, it works fine, but using a custom model does not. Thanks.
