Nintendo made a statement that Forever Blue is bugged and the source of the problem is the Shinonomesakatazame (pictured). The key to dodging the bug is to no put the Shinonomesakatazame in your aquarium. If it’s automatically put in your aquarium, you need to remove it otherwise the game is going to lock up. Also if you’re editing the aquarium and the Shinonomesakatazame is in it, do not press B and return to the boat. Follow these steps and you should be able to enjoy Forever Blue (unless you adamantly want a Shinonomesakatazame in your tank…).
While these are ways around the glitch, it’s probably best to keep two or three extra save files just in case something happens. Since Forever Blue still has a few more months before it becomes Endless Ocean in North America it seems likely Arika will fix the problem before then.
