I was playing as a ship, I had the setting on easy so had unlimited fuel.
Anyway I was part way through a mission doing well shelling and destroying enemy ships then I noticed I was slowing down.
I thought maybe I had took damage and hadn't noticed with all the excitement but no, everything seemed OK.
Eventually the ship stopped, still firing and destroying ships but no movement, I re-selected the engine options but nothing.

I exited the mission as I was a sitting duck but wondered why this happened, is it something I should or shouldn't have done?
