Just created an account for my friend and Tomb Raider was already removed from the Pro section. Manually finding it on the store shows no claim button either. Was it removed in error? December isn't over yet and both of Novembers games are still up.
Unfortunately they had announced the need to claim them by December 31st at 9am PT. Additionally, in that blog they also mentioned that the launch items (Destiny 2, Farming Simulator, Samurai Showdown) would remain. https://community.stadia.com/t5/Stadia-Community-Blog/This-Week-on-Stadia-Stadia-Pro-games-for-Janua... Because the catalog is so thin right now, I would not be surprised if it doesn't go back on sale price sooner than later.
