Thanks for reply. I have posted a short bug report that experience is not working. I have never seen a 1, 2 or 3 star ship in harbor permanently. On you tube there are gameplays of 18 episodes and no ships have any stars. If you put experienced land soldiers back to reserve and than to ships crew you get ships with stars in harbor but after a save and load action those stars dissapear and crew experience are reset to 1,1,1,1,1,1 you already wrote about. I was trying too look at ships crew experience before and after battle (removing officers not to complicate the view) and it seems not to work at all.
