Speaking of drones...
The Retourschip, the big Fuel Tanker, has two empty fighter slots with the default autofit having borers in them, but AFAIK you can't buy Borers and the autofit doesn't place anything in their place, why?
I know I can manually place something there instead, but this bothers me.
Hello again Shinr, I will try to help but I am a bit confused. The Standard variant for the Retourschip is equipped with a Tender and a Mizzen which both have the tag of support0. I just checked to make sure the variant goal was set to true and it is. I went in game and spawned an empty one in my current fleet and made sure I had some drones in my cargo that also had support 0, in this case mining drones, and when I autofit the 2 mining drones were in the slots.
I am unsure where borer drones come into play but the funny thing about Borer drones is they have no category tag in the vanilla wing_data, just nodrop,nosell, low. So in essense, as far as I know, the Borer would never be picked as an autofit wing unless the ship in question has them set as their variant goal and, as I state earlier, that is not the case for the Retourschip.
Gah here I go again with the TLDR, sorry about that.

However, I am committed to correcting any issues with my mods so any clarity you could provide is key for me to properly help.
