Problem with my round code?

Whenever it gets time to do roundtime, it already says the round is over. Help?

players = game.Players:GetPlayers()
h = Instance.new("Hint", workspace)

maps = game.ServerStorage:FindFirstChild("Maps"):GetChildren()
getsword = game.ServerStorage:FindFirstChild("Sword")

while wait(1) do
	if game.Players.NumPlayers >= 2 then
		h.Text = "Starting a new round!"
		wait(3)
		
		h.Text = "Choosing a random map..."
		wait(3)
		
		local chosenmap = maps[math.random(1, #maps)]:Clone()
		chosenmap.Parent = workspace
	
		h.Text = "The map is " .. chosenmap.Name .. " by " .. chosenmap.Creator.Value .. "!"
		wait(3)
		
		h.Text = "Teleporting players..."
		wait(3)
		
		for i, v in pairs(players) do
			if v.Character.Humanoid.Health > 0 and v ~= nil then
				local spawns = chosenmap:FindFirstChild("Spawns"):GetChildren()
				local sword = getsword:Clone()
				v.Character:MoveTo(spawns[i].Position)
				sword.Parent = v.Backpack
			end
		end
		
		local roundtime = 60
		local dead = 0
		
		while wait(1) and roundtime > 0 and dead < #players do
			h.Text = "Time until next round " .. roundtime
			roundtime = roundtime - 1
		end
		
		for i, v in pairs(players) do
			v.Character.Died:connect(function()
				dead = dead + 1
			end)
		end
		
		h.Text = "The time is up!"
		wait(3)
		
		for i, v in pairs(players) do
			if v.Character.Humanoid.Health > 0 and v ~= nil then
				v:LoadCharacter()
			end
		end
	else
		h.Text = "Waiting for another player..."
	end
end

You're doing GetPlayers() right when the server starts, which will always be 0. Let me fix this up for you. I actually also found a few other errors I fixed that had nothing to do with what you were wanting.

h = Instance.new("Hint", workspace)

maps = game.ServerStorage:FindFirstChild("Maps"):GetChildren()
getsword = game.ServerStorage:FindFirstChild("Sword")

while wait(1) do
    if game.Players.NumPlayers >= 2 then
        h.Text = "Starting a new round!"
        wait(3)

        h.Text = "Choosing a random map..."
        wait(3)

        local chosenmap = maps[math.random(1, #maps)]:Clone()
        chosenmap.Parent = workspace

        h.Text = "The map is " .. chosenmap.Name .. " by " .. chosenmap.Creator.Value .. "!"
        wait(3)

        h.Text = "Teleporting players..."
        wait(3)
	local players=game.Players:GetPlayers() --set the players value here
        for i, v in pairs(players) do
            if v.Character.Humanoid.Health > 0 and v ~= nil then
                local spawns = chosenmap:FindFirstChild("Spawns"):GetChildren()
                local sword = getsword:Clone()
                v.Character:MoveTo(spawns[i].Position)
                sword.Parent = v.Backpack
            end
        end

        local roundtime = 60
        local dead = 0

        while wait(1) and roundtime > 0 and dead < #players do
            h.Text = "Time until next round " .. roundtime
            roundtime = roundtime - 1
        end

        for i, v in pairs(players) do
	if v and v.Character and v.Character:FindFirstChild("Humanoid") then --added failcheck
            v.Character.Humanoid.Died:connect(function() --died is an event in humanoid, not player
                dead = dead + 1
            end)
	end
        end

        h.Text = "The time is up!"
        wait(3)

        for i, v in pairs(players) do
            if v.Character.Humanoid.Health > 0 and v ~= nil then
                v:LoadCharacter()
            end
        end
    else
        h.Text = "Waiting for another player..."
    end
end
