So I redid a training test On version 1.9, and there? Very good surprise, indeed it would seem that the fleet, apart from the morale of the crew of course, there are no more worries with the excessive consumption of fuel as well as MSP.
Maybe it was a 1.8 bug ?, Still, that training is now much easier to manage.
My fleet began training on October 8, 2030. On August 30, 2031, the deployment time was exceeded by 9.57 months. Knowing that their time is 12 months.
Here is the image of my fleet:
In green, we can see that now everything is good for ships. On the other hand, for the crew ... It's hard military life!
