Finding Function Issue

[lor5s]

So, a few weeks back I started making my pathfinding, it works great, only when it finally kills an enemy, it cant find any more enemies. I’ve narrowed it down to this finding function, help?

local function find()
	local en
	for i, v in pairs(workspace.BOTS.Enemies.Pirates:GetChildren()) do
		if v then
			if v:FindFirstChild("HumanoidRootPart") then
				if (v.HumanoidRootPart.Position - script.Parent.HumanoidRootPart.Position).Magnitude < stuff.findrange and v.Humanoid.Health > 0 then
					en = v.HumanoidRootPart
					return en
				end
			end
		end
	end
	for i, v in pairs(workspace.BOTS.Enemies.WaterBois:GetChildren()) do
		if v then
			if v:FindFirstChild("HumanoidRootPart") then
				if (v.HumanoidRootPart.Position - script.Parent.HumanoidRootPart.Position).Magnitude < stuff.findrange and v.Humanoid.Health > 0 then
					en = v.HumanoidRootPart
					return en
				end
			end
		end
		for i, v in pairs(workspace.BOTS.Enemies.Goblins:GetChildren()) do
			if v then
				if v:FindFirstChild("HumanoidRootPart") then
					if (v.HumanoidRootPart.Position - script.Parent.HumanoidRootPart.Position).Magnitude < stuff.findrange and v.Humanoid.Health > 0 then
						en = v.HumanoidRootPart
						return en
					end
				end
			end
		end
		for i, v in pairs(workspace.BOTS.Bad:GetChildren()) do
			if v then
				if v:FindFirstChild("HumanoidRootPart") then
					if (v.HumanoidRootPart.Position - script.Parent.HumanoidRootPart.Position).Magnitude < stuff.findrange and v.Humanoid.Health > 0 then
						en = v.HumanoidRootPart
						return en
					end
				end
			end
		end
	end
	for i, v in pairs(game.Players:GetChildren()) do
		if (v.Character.HumanoidRootPart.Position - script.Parent.HumanoidRootPart.Position).Magnitude < stuff.findrange and v.Character.Humanoid.Health > 0 then
			if v.Character.HumanoidRootPart:FindFirstChild("Bad") then
				en = v.Character.HumanoidRootPart
				return en
			end
		end
	end
end
