This script only runs sometimes... why might that be?

I've got a script which handles certain RemoteEvents; this is the code at the beginning to connect the events.

wait()
game.Workspace.PlayerLeaveArmory.OnServerEvent:connect(function(plr, args) changeLoadout(plr, args[1]) end)
print("Connection")
game.Workspace.PartAnchor.OnServerEvent:connect(function(plr, args) anchorPart(args[1], args[2]) end)
print("Connection")
game.Workspace.ModifyLoadout.OnServerEvent:connect(function(plr, args) modify(plr, args[1], args[2], args[3], args[4]) end)
print("Connection")	
game.Workspace.SelectLoadout.OnServerEvent:connect(function(plr, args) select(plr, args[1], args[2])end)
print("Connection")

function loadContainsType(load, weapon)
	local type = weapon.WeaponType.Value
	if type == "Guns" then . . .

functions referenced above

The printouts of "Connection" almost never happen, but when they do, then the script works fine. However, sometimes I have to disable and re enable the script from the Server console in order to make it start working.

The script is pasted into game.Workspace and Enabled by a different script 1 second after all of the RemoteEvents are created and put in Workspace; right at the startup of a server.

As said in the question, this script only connects the events sometimes, and I'm not sure what's causing to work/not work. Thoughts?

Here's the script that pastes the other script and enables it:

--Ensures that a different script isn't setting up the events; in case a duplicate of the model that
--Owns this script exists
if game.Workspace:FindFirstChild("ArmoryEventsSetup") == nil then
	setup = Instance.new("BoolValue")
	setup.Name = "ArmoryEventsSetup"
	setup.Parent = game.Workspace
	
	--Sets up the client side of the Remote Events
	game.Players.PlayerAdded:connect(function(player)
		player:WaitForChild("Backpack")
		local event = Instance.new("RemoteEvent")
		event.Parent = player.Backpack
		event.Name = "PlayerEnterArmory"
		script.ArmoryClient:clone().Parent = player.Backpack
	end)	
	
	wait(1)

	local event = Instance.new("RemoteEvent")
	event.Parent = game.Workspace
	event.Name = "PlayerLeaveArmory"
	
	local event = Instance.new("RemoteEvent")
	event.Parent = game.Workspace
	event.Name = "PartAnchor"	
	
	local event = Instance.new("RemoteEvent")
	event.Parent = game.Workspace
	event.Name = "ModifyLoadout"	

	local event = Instance.new("RemoteEvent")
	event.Parent = game.Workspace
	event.Name = "SelectLoadout"
		
	script.ArmoryServer:Clone().Parent = game.Workspace
	wait(1)
	game.Workspace.ArmoryServer.Disabled = false
	

else
	script:remove()
end
