How do I make a round end when the core is destroyed?

I'm making a core defense game and I'm having problems. I want the loop to return to the beggining when the core is destroyed and I also want the round timer to stop, I've looked but cant find the solution to any.

RoundManager ServerScriptService ServerScript

local status = game.ReplicatedStorage.Status
local players = script.Players
local maps = game.ServerStorage.Maps:GetChildren()
local Spectating = game.Teams["Lobby/Spectating"]
local DTeam = game.Teams.Defenders
local RTeam = game.Teams.Raiders
local MorphRoomD = game.Workspace.MorphRoomD
local MorphRoomR = game.Workspace.MorphRoomR
local playersneeded = 1
local roundlength = 500
local intermissionlength = 30

local function checkplayers()
	if players.Value >= playersneeded then
		return true
	else
		return false
	end
end

local function IntermissionTimer()
	for i = intermissionlength, 0, -1 do
		wait(1)
		status.Value = "Intermission: "..i.." seconds left!"
	end
end

local function RoundTimer()
	for i = roundlength, 0, -1 do
		wait(1)
		status.Value = "Round In Progress: "..i.." seconds left!"
	end
end


local function Map()
	local randomchosenmap = maps[math.random(1,#maps)]
	status.Value = "Map Chosen!"
	wait(1)
	status.Value = "The Chosen map will be "..randomchosenmap.Name.."!"
	mapclone = randomchosenmap:Clone()
	mapclone.Parent = workspace
	core = mapclone.Core

	local morphRoomSpawnsD = MorphRoomD.Spawns:GetChildren()
	local morphRoomSpawnsR = MorphRoomR.Spawns:GetChildren()

	for i,player in pairs(game.Players:GetPlayers()) do
		if player.Team == DTeam then
			local char = player.Character or player.CharacterAdded:Wait()
			local RandomMorphRoomSpawnD = morphRoomSpawnsD[math.random(1,#morphRoomSpawnsD)]
			char.HumanoidRootPart.CFrame = RandomMorphRoomSpawnD.CFrame
		elseif player.Team == RTeam then
			local char = player.Character or player.CharacterAdded:Wait()
			local RandomMorphRoomSpawnR = morphRoomSpawnsR[math.random(1,#morphRoomSpawnsR)]
			char.HumanoidRootPart.CFrame = RandomMorphRoomSpawnR.CFrame
		end
	end
end

local function destroyMap()
	mapclone:Destroy()
end

local function reloadAllPlayers()
	for i,player in pairs(game.Players:GetPlayers()) do
		player:LoadCharacter()
	end
end

while wait() do
	if checkplayers() then
		IntermissionTimer()
		Map()
		RoundTimer()
		reloadAllPlayers()
		destroyMap()
	end
end

How would I implement that into my script?

If the core was destroyed, you would fire an event to end the round something like this might work

local function RoundTimer()
    for i = roundlength, 0, -1 do
        wait(1)
        status.Value = "Round In Progress: "..i.." seconds left!"
	if Core == nil then
		break
	end
    end
end

Please tell me if this doesn't work or if someone notices a flaw!
