Why is the script constantly repeating itself on different parts of the code?

So far I have no clue why the script repeats itself constantly even when it's disabled. What happens is it restarts at a certain point in the script, specifically it restarts around "GameMessage.Text = "The timer has started and NPCs have spawned. Good luck!" Even when the script is disabled, and if I re-enable it as well, it's like they're running two different sections of the code at the same time.

GameMessage connects to a global function which spawns a GUI for a certain amount of seconds.

Also, I put teemo a lot. Teemo #1.
