Infinite yield possible on 'Workspace.Felipe:WaitForChild("humanoid")'?

I'll explain my situation. so this is a Round script or intermission script you'll notice that when looking at my script below,so when you join a game and the first round start, its fine,but on the second round this is where everything will break.

for i = GameTime, 0, -1 do
        if game.Workspace.Felipe:WaitForChild("humanoid").Health == 0  then
            print("STOP")
            break
        elseif game.Workspace.Felipe:WaitForChild("humanoid").Health ~= 0  then
            print("COUNT")
            ChangeText('GameTime ' ..i)
            wait(1)
        end
    end

this is where the error is found,the error only shows when on the second round. is there something im missing? cause im confused af. please help!
