Ok, new question: Is there a limit to the number of fleets you can have?
The reason I ask is that I'm in a game now where I have between 30 & 35 fleets and a very wierd thing just happened. I assembled a fleet of about 35 ships at a training world and sent it on its way, but on the next turn all the ships had stopped after moving the expected distance but their "fleet" had disappeared. All the 35 ships were in the same sector awaiting orders.

Then I had to send them back to my training world to become part of another trained fleet.
Anyone else ever see a fleet disappear from under its ships?
