Description: managed to occupy comet, which is very bad cause it ran out of fuel and there is no way to give it more.
Actions required to repeat the problem:Alright so this is how you can occupy a comet; the first thing you need to do is attack and occupy a planet. After you do that you need to attack a comet, but while in combat at the comet send a unit currently in the combat to attack the comet again. The result is that the unit or units do not have the neeeded fuel to return to the occupation they came from. However, they still inherite the flight features of occupation and will thus occupy the comet. There is no way to give them fuel as you cannot occupy a comet in any other way. (the command simply doesn't exist, nor does transport and attack command with extra fuel doesnt reful the occupying fleet. I know because i tried all of these things.) i had to get someone to drop friendship with me and attack my trapped keeper in order to free up the fleet slot.
