Fully account for Streaming

[1ForeverHD]

1. Ensure :getRandomPoint() returns nil instead of recurring infinitely if zone parts are 0, e.g. if all streamed all:

   function Zone:getRandomPoint()
   local region = self.exactRegion
   local size = region.Size
   local cframe = region.CFrame
   local random = Random.new()
   local randomCFrame
   local success, touchingZoneParts
   local pointIsWithinZone
   local totalPartsInZone = #self.overlapParams.zonePartsWhitelist.FilterDescendantsInstances
   if totalPartsInZone <= 0 then
       -- Its important we return if there are no parts within the zone otherwise the checks below will recur infinitely.
       -- This could occur for example if streaming is enabled and the zone's parts disappear on the client
       return nil
   end
   repeat
       randomCFrame = cframe * CFrame.new(random:NextNumber(-size.X/2,size.X/2), random:NextNumber(-size.Y/2,size.Y/2), random:NextNumber(-size.Z/2,size.Z/2))
       success, touchingZoneParts = self:findPoint(randomCFrame)
       if success then
           pointIsWithinZone = true
       end
   until pointIsWithinZone
   local randomVector = randomCFrame.Position
   return randomVector, touchingZoneParts
   end

2. line 87 of tracker so that it accounts for parts being streamed in:

   local function playerAdded(player)
   local function charAdded(character)
       local function trackChar()
           local hrp = character:WaitForChild("HumanoidRootPart", 0.1)
           local humanoid = character:WaitForChild("Humanoid", 0.1)
           local head = character:WaitForChild("Head", 0.1)
           if hrp == nil or humanoid == nil or head == nil then
               return
           end
           updatePlayerCharacters()
           self:update()
           for _, valueInstance in pairs(humanoid:GetChildren()) do
               if valueInstance:IsA("NumberValue") then
                   valueInstance.Changed:Connect(function()
                       self:update()
                   end)
               end
           end
       end
       local hrp = character:FindFirstChild("HumanoidRootPart")
       if hrp then
           task.delay(0.1, trackChar)
       else
           character.ChildAdded:Connect(function(child)
               if child.Name == "HumanoidRootPart" and child:IsA("BasePart") then
                   task.delay(0.1, trackChar)
               end
           end)
       end
   end
   if player.Character then
       charAdded(player.Character)
   end
   player.CharacterAdded:Connect(function(char)
       charAdded(char)
   end)
   player.CharacterRemoving:Connect(function(removingCharacter)
       self.exitDetections[removingCharacter] = nil
   end)
   end
