Unless I’m being extremely unimaginative, how do you fan edit in a new threat, like a black hole, if none of the characters are reacting to the fact they’re limited because of a black hole? They’re all reacting to low fuel and the barrage of fire from the First Order. Neither will the First Order acknowledge the threat, such as a black hole, preventing them from being able to hyperspace in front of them because this issue wasn’t even an issue brought up or anything similar within the film.
