I put the ship in minister control.
All turns i receive the same message from the same ship in the same location.
I know that i can put it in manual control, but is a bug.
Yes, the AI sometimes gets its stellar manipulations out of order. I think it can't tell the difference between a nebula system and a regular system. Or maybe it gets confused if it doesn't have a 'destroy nebula' ship when it needs one and just goes on to the next step?
