The explorer tech mentions unlocking several augment slots that affect things like survey speed. How do I put these on an explorer? When I click the right slot, it only shows my unlocked afterburner.

Well, I just checked the files and noticed that the special slots for those features are currently commented out in the code. The funny thing is I cannot remember WHY we turned those off, I assume there was a bug or issue somewhere but I can't remember. I'll look into this when we start working on the next update.
