I am aware of the curator connect issue where people are receiving keys through the platform and are reporting not owning the game. I, do not currently own my own game. This is because the reviewer build and the developer build do not exist and were removed by steam in that tangled mess during the retirement of the Armeida Tactics DLC. (Honestly that little mini-game has given me more trouble than it's been worth). Steam Support is looking into it as we speak and I hope to find a solution soon!
