So I bought Beholder a few months ago played it and then I needed storage so I deleted it. Now I want to play it again and this is what I see. When I go on the game's page it says start I press it and then it says:"This game is not available on the Playstation store." And I can't see the game anywhere else and I can't even delete it pls help.
