Thank you, I should check for sure again. It seemed to me that after they left the asteroid field it was 1/1 and then for the next bunch of turns it was still 1/1 because I built a new mining ship, the new mining ship was eta 4 turns to the new mining area, but the original mining ship that you start with was eta 24 turns, because its movement was now 1/1. I usually play with the speed bonus +2, so that my ships move as fast as possible. I will do a better more thorough check to see if it is temporary, it seems to me that it is not, but I am not 100% till I check again. Thank you so much for the answers and the quick responses.
