Errr i tried to put x2 Docking Range Booster , it looked to work (i think) , did you tried ? Now with new mining mission it's not very useful i think (who allow you to upgrade captains, and maybe create Miners Captains, idk). Mission do not use ressources in sectors i think, but you can still mine manually to gather a sector where you spotted nice asteriods.
I did like you 😄 I made my "nero" from Star Trek, i converted a pirate mothership into a mining carrier full of R-mining roid 42 dps in xanion for now. i'll put a screen when he ll be back from his new 2 hour mission 😄 my captains are only level 1 -rank 0 for now 😄. I just bought somes few sec ago, idk their english names, but i think they are for trading thoses i got (its guys from station where you can hack / sell stolen stuff)
