So I have been doing a lot of Bug Testing in ROBLOX Studio and everything seems to work fine. However, whenever I instantiate a part into workspace (manually, not using "Instance.new()"), workspace:Raycast().Instance returns nil! Normally, if the ray doesn't intersect any parts, workspace:Raycast() will return nil, but in this case, workspace:Raycast().Instance returns nil, which is unheard of and never happens unless I instantiate (manually) a part into workspace! Here is my code:

Local script

local RAY_PARAMS = RaycastParams.new()
	RAY_PARAMS.FilterDescendantsInstances = IgnoredParts
	RAY_PARAMS.FilterType = Enum.RaycastFilterType.Blacklist
	
	local RAY_RESULT = workspace:Raycast(Muzzle.Position, (mouse.Hit.Position - Muzzle.Position).Unit * WeaponData.Range, RAY_PARAMS)
	
	if RAY_RESULT == nil then -- If the ray doesn't intersect any parts.
		wait(WeaponData.FireRate)
		shooting = false
		return
	end
	
	local part, pos = RAY_RESULT.Instance, RAY_RESULT.Position
	local damage = 0
	
	if part then

		if part.Parent:FindFirstChild('Humanoid') then
			if part.Name == 'Head' then
				damage = WeaponData.HeadDamage
			else
				damage = WeaponData.Damage
			end
		end
		
		Events.Shoot:FireServer(part, pos, damage)
	end

Server script

Events.Shoot.OnServerEvent:Connect(function(player, part, pos, damage)
	
	local humanoid = part.Parent:FindFirstChild('Humanoid') -- Where the errors are coming from.
	print('Ray hit: ' .. part.Name)
	
	if humanoid then
		humanoid:TakeDamage(damage)
	else
		
		local bullet_hole = Instance.new('Part')
		bullet_hole.Anchored = true
		bullet_hole.CanCollide = false
		bullet_hole.BrickColor = BrickColor.new('Really black')
		bullet_hole.Material = Enum.Material.SmoothPlastic
		bullet_hole.Size = Vector3.new(0.1, 0.1, 0.1)
		bullet_hole.Position = pos
		bullet_hole.Parent = workspace.RayIgnoredParts
		
		game:GetService('Debris'):AddItem(bullet_hole, 5)
		
	end
	
end)

Of course, I'm not checking to see if the part is nil, but it shouldn't. The "Instance" property in workspace:Raycast().Instance happens to be nil even though the ray hits a part. Can someone help me with this problem?

EDIT: This might be some internal ROBLOX bug. I rewrote my Server script and this is what it looks like:

Events.Shoot.OnServerEvent:Connect(function(player, part, pos, damage)
	
	local humanoid = nil
	
	if part then
		humanoid = part.Parent:FindFirstChild('Humanoid')
		print('Ray hit: ' .. part.Name)
	else
		print('Ray hit: INSTANCE_NIL')
	end
	
	if humanoid then
		humanoid:TakeDamage(damage)
	else
		
		local bullet_hole = Instance.new('Part')
		bullet_hole.Anchored = true
		bullet_hole.CanCollide = false
		bullet_hole.BrickColor = BrickColor.new('Really black')
		bullet_hole.Material = Enum.Material.SmoothPlastic
		bullet_hole.Size = Vector3.new(0.1, 0.1, 0.1)
		bullet_hole.Position = pos
		bullet_hole.Parent = workspace.RayIgnoredParts
		
		game:GetService('Debris'):AddItem(bullet_hole, 5)
		
	end
	
end)

I found out that workspace:Raycast().Instance returns nil when instantiating (manually) parts to the workspace, but workspace:Raycast().Position doesn't. If the problem is just me, please provide me with a clear answer.
