No, definitely different things, that was pretty clearly stated - patch was released, and the DLC would be available from Steam later. I updated to 1.0.169 before the DLC showed up on Steam. And I still can't enable the new DLC in the game - it acts exactly the same as the Source Hunter DLC (which I do not own and so cannot enable.) Basically it's listed, but I can't check that box to enable it in the list.

Anyone got this working?
