PBW: My ships can't move

[Gorgo]

This game I've created is turning against me...
Next turn, fleet that started the problem dissolved, tried to move ships into different directions - nothing moves!

Puke: I don't use any mod, just standar 1.41 for which I've created the game.
I have the impression that I also can't launch satellites at the moment, yet I could be wrong at that. Building stuff works.
I run another game on PBW with the same install where no problems of that kind occured, and this game is in the year 2410.

Rich04: I have the problem in two different systems. Both fleets are 3 - 5 ships, it's about the year 2404. Right now I'm trying what you suggested, turning all ministers on and off again. I had to make peace with my neighbour I had just started war with - depressing if you're playing a psychotic and bloodthirsty race!
