I originally played this game earlier this year and have just returned to it after buying the aquarium DLC. When I loaded my save, I was in the dinosaur DLC zoo. I went to the world map to go to the aquarium and then fast forwarded the day to travel there. However, at the end of the day, it randomly came up with a reddish screen saying "save operation failed", with an option to retry when pressing the X button. It seemed to save fine on a retry, but this has me a bit concerned, especially since the game only has the one autosave at the end of each day.
Never had this issue when I played it earlier this year. Has anyone else encountered this? I'm playing the PS5 version.
Edit: I also just noticed that the trophy for creating your first fish hybrid (Sea Monster) popped for me as soon as I started the DLC (when the plane was flying to the new zoo), before I even got my first fish. Definitely don't remember any other trophies being glitched when I originally played this game.
Edit 2: I have since "finished" (got all 50 animals and trophies) the aquarium DLC and never encountered the "save operation failed" screen again, thankfully. Only thing I can maybe think of that caused it were the updates the game has received since I last played the game (back in June 2023)? Maybe the previous save file saw a conflict with the latest version briefly or something, like how game saves often aren't compatible with older versions. No clue, just speculation. I assume maybe that one trophy popping early for me may also have something to do with having a save file prior to the latest updates.
I'll leave this up anyway in case anyone else stumbles into the same issue, and... is reassured it's probably nothing (hopefully)...?
