Help With :Destroy()?

I have a script where my game cycles through three phases, the lobby phase, loading phase, and the game phase.

However at the end of the game phase, the bricks that have been cloned in are not being destroyed, and there are no errors.

Here is my code (btw the lt, l2t, and gt are intvalues representing the amount of time left in a specific phase):

--{{VARIABLES}}--
g = game.Workspace.gameRunner.inGame
s = g.Parent.status
gt = game.Workspace.gameRunner.gameTime
lt = game.Workspace.gameRunner.lobbyTime
l2t = game.Workspace.gameRunner.loadTime
--{{CHECKER}}--
while true do
	if l2t.Value == 15 then
		wait(1)
		game.ServerStorage.Fallen:MakeJoints()
		game.ServerStorage.Fallen:Clone().Parent = game.Workspace
		game.Workspace.Fallen.Name = "fallenCopy"
	elseif gt == 1 then
			game.Workspace.fallenCopy:Destroy()
	end
	wait(1)
end

Here is another idea for a solution which also did not work:

--{{VARIABLES}}--
g = game.Workspace.gameRunner.inGame
s = g.Parent.status
gt = game.Workspace.gameRunner.gameTime
lt = game.Workspace.gameRunner.lobbyTime
l2t = game.Workspace.gameRunner.loadTime
--{{CHECKER}}--
while true do
	if l2t.Value == 15 then
		wait(1)
		game.ServerStorage.Fallen:MakeJoints()
		game.ServerStorage.Fallen:Clone().Parent = game.Workspace
		game.Workspace.Fallen.Name = "fallenCopy"
		end
		if gt == 1 then
			game.Workspace.fallenCopy:Destroy()
	end
	wait(1)
end

A solution would be highly appreciated as I have been stumped on this for a while!
