I recently finished Pragmata (Very highly recommended), and thought I'd complete Collisto Protocol. But when I went to search it, it asked me to purchase the game. We got it with PS+ in October of 2023 and I put an hour or 2 into it, but now it's as if I never owned it in the first place. Is anyone else having a similar issue, and if so, how did you remedy it? Thanks in advance for any and all help.
