Greetings.
I know this has been an ongoing problem. I just started playing Galciv again and my current game has become unplayable due to this bug. They seemed to fleet up early on, but now almost never send fleets, and when they do they are undermanned. They have a lot of ships, but just stack them single sometimes 50 or 60 deep. This makes my game a mop up exercise when it would have been very competitive. I use no mods. Insane map size with 24 opponents. Is this something they are working on? Other than this bug I am loving the game so far with all the changes.
