Yes, I admit my part of guilt here. But I searched on SteamGifts with parameter to exclude owned DLCs. And in most of the cases it works fine, just for whatever reasons it fails over and over on these puzzle DLCs. I own lot of games and in my head I loss track of what I have and what not. And especially with these Jigsaw Puzzle, because there are tens of such games and each having several DLCs. These asset flip puzzles from the same developer has over hundred of DLCs with just slight different names and numbers. I own some and some I don't. I admit, it is my fault to trusting SteamGifts filter. That's true.
