This is a big one. I can't find the conflict in these two scripts. Help?

I made a game called Random BattleGrounds of Randomness 2 and I used the Disaster Kit V2 the I've modified as a base for the game as it could do stuff I wanted to do in the game and I figured it'd make it a bit easier. Well, now I'm looking to update the game with a K/D leaderboard but when I do it breaks the disaster kit. Normally, in the game, it has a 90 second timer between disasters (Which are labeled Hazards in my game), when the timer reaches 0 a disaster plays, afterwards the timer counts back down again. However, when I try to use a Leaderboard script along with it it just breaks and I can't figure out why, I assume there's a conflict somewhere. I've tried everything I could think of, but being pretty novice when it comes to Lua I've run out of ideas.

Here's the Leaderboard script:

local Players = game.Players

local Template = Instance.new 'BoolValue'
Template.Name = 'leaderstats'

Instance.new('IntValue', Template).Name = "Kills"
Instance.new('IntValue', Template).Name = "Deaths"


Players.PlayerAdded:connect(function(Player)
    wait(1)
    local Stats = Template:Clone()
    Stats.Parent = Player
    local Deaths = Stats.Deaths
    Player.CharacterAdded:connect(function(Character)
        Deaths.Value = Deaths.Value + 1
        local Humanoid = Character:FindFirstChild "Humanoid"
        if Humanoid then
            Humanoid.Died:connect(function()
                for i, Child in pairs(Humanoid:GetChildren()) do
                    if Child:IsA('ObjectValue') and Child.Value and Child.Value:IsA('Player') then
                        local Killer = Child.Value
                        if Killer:FindFirstChild 'leaderstats' and Killer.leaderstats:FindFirstChild "Kills" then
                            local Kills = Killer.leaderstats.Kills
                            Kills.Value = Kills.Value + 1
                        end
                        return 
                    end
                end
            end)
        end
    end)
end)

And here's the game script:

local dataStore = require(game.ServerStorage.DataStore)
local survivors = {}
local currentDisaster = nil
local timeToCount = 0
local rounds = 0
local states = Instance.new("Folder")
states.Name = "PlayerStates"

local lighting = game:GetService("Lighting")

function regenStructures()
    workspace.Structures:ClearAllChildren()
    local maps = game.ServerStorage.Clones.Maps:GetChildren()
    local mapCopy = maps[math.random(1, #maps)]:Clone()
    mapCopy.Parent = workspace.Structures
    mapCopy:MakeJoints()
end

function compilePlayers()
    local names = ""
    if #survivors == 1 then return survivors[1] end
    for i = 1, #survivors do
        if i == #survivors then
            names = names.. "and ".. survivors[i]
        else
            names = names.. survivors[i] .. ", "
        end
    end
    return names
end

function died(playerName, humanoid)
    if humanoid and humanoid.Health == 0 then
        for i, v in pairs(survivors) do
            if v == playerName then
                table.remove(survivors, i)
            end
        end
    end 
end

function destroyMessage()
    for i, v in pairs(workspace:GetChildren()) do
        if v:IsA("Message") then
            v:Destroy()
        end
    end
end

function createOrUpdateMessage(msg)
    if workspace:FindFirstChild("_Message") then
        workspace["_Message"].Text = msg
    else
        local message = Instance.new("Message")
        message.Name = "_Message"
        message.Text = msg
        message.Parent = game.Workspace
    end
end

function destroyHint()
    for i, v in pairs(lighting:GetChildren()) do
        if v:IsA("StringValue") then
            v.Value = ""
        end
    end
end

function createOrUpdateHint(msg)
    if lighting:FindFirstChild("_Hint") then
        lighting["_Hint"].Value = msg
    else
        local message = Instance.new("StringValue")
        message.Name = "_Hint"
        message.Value = msg
        message.Parent = game.Lighting
    end
end

function countDown(cdt, msg)
    for i = 1, cdt do
        createOrUpdateHint(msg .. cdt - i + 1)
        wait(1)
    end
end

function _G.updateLeaderboard()
    for i, v in pairs(game.Players:GetChildren()) do
        local leaderstats = v:FindFirstChild("leaderstats")
        if leaderstats then
            local fakePoints = leaderstats:FindFirstChild("Points")
            local fakeSurvivals = leaderstats:FindFirstChild("Survivals")
            fakePoints.Value = dataStore:GetStat(v, "Points") or 0
            fakeSurvivals.Value = dataStore:GetStat(v, "Survivals") or 0
        end
    end
end

regenStructures()
while true do
    if rounds == roundsToRegenStructures then
        regenStructures()
        rounds = 0
    end 
    rounds = rounds + 1
    countDown(breakTime, "Oh no! A Hazard is coming in ")
    _G.updateLeaderboard()
    destroyHint()
    local connections = {}
    survivors = {}
    for i, v in pairs(game.Players:GetChildren()) do
        if v.Character and v.Character:FindFirstChild("Humanoid") then
            table.insert(survivors, v.Name)
            table.insert(connections, 
                v.Character.Humanoid.HealthChanged:connect(function() 
                    died(v.Name, v.Character.Humanoid) 
                end)
            )
        end
    end
    currentDisaster = disasters[math.random(#disasters)]
    if game.ServerStorage.Disasters:FindFirstChild(currentDisaster[1]) then -- disaster exists, proceed to spawn it
        --
        local disasaterCopy = game.ServerStorage.Disasters[currentDisaster[1]]:clone()
        disasaterCopy.Parent = game.Workspace
        disasaterCopy:makeJoints()
        countDown(currentDisaster.Duration, "Watch Out! Active Hazard " .. currentDisaster[1] .. " will be leaving in ")
        destroyHint()
        disasaterCopy:Destroy()
        --
        for i, v in pairs(survivors) do
            local player = game.Players:FindFirstChild(v)
            if player then
                dataStore:AddStat(player, "Points", currentDisaster.Points) -- award survivors points
                dataStore:AddStat(player, "Survivals", 0) -- award survivors 1 survival
            end
        end
        _G.updateLeaderboard()
        wait(3)
        destroyMessage()
    else
        -- warn dev
        createOrUpdateHint('ERROR: The game has failed to locate "' .. currentDisaster[1] .. '" in the Disasters folder in ServerStorage.')
        while true do
            wait(1)
        end
    end
end

What it ends up doing is, when the timer gets to 0, it just sits there. No disaster spawns, it doesn't reset the timer, it just does nothing.

Any help would be appreciated
