I think it's not.

If you check Fatigue page, there is information about when your ship's morale is 30-39 there is a slight Evasion and Accuracy decrease and Mamiya/Irako button will blinking when there are ship in your fleet that have morale lower than 40.

So, it's just telling you about that while original game not.
