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
