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
