[CLOSED] For loop stopping for no apparent reason?

below is a script with zero errors:

players = game.Players:GetPlayers()
while true do
	wait(1)	
	print("test")
	for i,v in pairs(players) do
		print("test2")
		local character = v.Character or v.CharacterAdded:Wait()
		repeat
			wait()
		until character
		local humanoid = character:WaitForChild("Humanoid")
		if character:FindFirstChild("thirst").Value <= 20 then 	
			humanoid.Health = humanoid.Health - 40	
		end
		if character:FindFirstChild("hunger").Value <= 20 then 	
			humanoid.WalkSpeed = 5	
		else	
			humanoid.WalkSpeed = 12	
		end
		tick()
	end
end

no errors? then what is the problem? you may ask, I have no clue... where does it stop? it stops at the part where it says:

for i,v in pairs(players) do

it prints "test" but not "test2"

EDIT: i found out to fix it i had to put :getplayers into the while loop and make it local
