Why is this script that 'regens' a model not working?

So this is in a game script I am making for a game. For some reason, it only works once in the beginning of the first round, but won't work in the second round.

Output gave me nothing and I have no idea what is the problem. Can someone please help me? Here's the script:

--[[
All of the variables and such are defined. I will only be posting the ones that I suspect are part of this issue.
--]]

local back = game.ServerStorage:WaitForChild("BackUp")
local clone = back:clone()
local time2remove = game.Workspace:WaitForChild("Item")

function Respawn()
    time2remove:remove()
    wait(0.01)
    clone.Parent = game.Workspace
    clone.Name = "Item"
end

while wait() do
    if NewGameMustStart.Value == true then
        NewGameMustStart.Value = false
        msg.Parent = game.Workspace
        msg.Text = "Welcome!" 
        wait(3)
        msg.Text = "A new game is beginning! Sit tight!"
        wait(3)
        msg.Text = "Game Beginning!"
        wait(2)
        Respawn()
        GameOn.Value = true 
        msg:remove()
    end
end --- There's more to this script, but I'm only posting the parts that matter in this issue.
