Why does the script skip the intermission if it goes from 2 to 1 players?

I've been trying to make a minigames script for a while now, but I can't fix all of the errors for the life of me. My most recent error is that if the game goes from having two players to one player during the intermission, it skips it completely and goes into the round. Thanks in advance for finding the error.

MapStorage = workspace.MapStorage
IntermissionTime = 15
Players = game.Players:GetChildren()
_G.RoundInProgress = false
NumPlayers = game.ReplicatedStorage.NumPlayers
NumPlayers.Value = 0
GameTime = 90

game.Players.PlayerAdded:connect(function(plr)
	NumPlayers.Value = NumPlayers.Value + 1
end)

game.Players.PlayerRemoving:connect(function(plr)
	NumPlayers.Value = NumPlayers.Value - 1
end)

        for i = IntermissionTime, 0, -1 do

On line 25. You put:

if NumPlayers.Value < 2 then break end

"break" breaks the loop, in other words, it will stop the "for" loop and immediately continue from line 30. It basically tells the game: If the number of players is less than two, break the loop (i.e skip the intermission.)

Also, instead of using a value for NumPlayers, why not just use #game.Players:GetPlayers() everytime you want to use it. It updates automatically by getting how many people are in the game.
