I recently bought the Dead Island Definitive Collection and have been having issues with Dead Island Riptide. The disc is in my PlayStation 5; everything works fine with the first game and the Ryder DLC, but I can't play Dead Island Riptide... I just can't find it, and I can't download it either. I even looked in the PlayStation Store, but it doesn't give me that option there either. Is there a solution to this problem?
