Help with :IsAncestorOf?

Code;

local event = Instance.new("RemoteEvent")
event.Parent = game.ReplicatedStorage
event.Name = "RCL"
event.OnServerEvent:connect(function()
        local gunsadded = false
        local bricktops = game.ReplicatedStorage.Maps.Bricktops
        for i,v in ipairs(game.Players:GetChildren()) do
        v.CharacterAdded:connect(function(character)
        if v.TeamColor == BrickColor.new("Sand red") or v.TeamColor == BrickColor.new("Sabd blue") then 
    if game.Workspace.CurrentMap:IsAncestorOf(game.ReplicatedStorage.Maps.Bricktops) then           for i,x in ipairs(WeaponStorage.RCLWeapons:GetChildren()) do
                if not gunsadded then
                gunsadded = true
                if x:IsA("Tool") then
                    x:Clone().Parent = v.Backpack
                               gunsadded = false
                            end
                        end
                    end
                end
            end
        end)
end

Purpose;

The event gets all the players in the game, and checks if they're on either the Bright blue or Bright red team, and checks whether "Bricktops" is present within workspace.CurrentMap. If the players are on the blue and red teams and Bricktops is present, then it gives the players weapons every time they respawn.

Idea of what the problem is;

if game.Workspace.CurrentMap:IsAncestorOf(game.ReplicatedStorage.Maps.Bricktops) then

Notes;

RemoteEvent is fired in another script when a TextButton is clicked.

Everything was running somewhat smoothly last night until I added :IsAncestorOf

I also tried using :IsDescendantOf
