So I spent some time out in the middle of freaking nowhere and did nothing more than exo and scanned some systems - every one of them I had never been to. If they had bio signals, I was stopping off. Spent a lot of time looking for some of these, particularly bacterium. Holy hell, those are the worst and can really burn your time up on a planet.
At any rate, I was 54% into Compiler (Before that reset debacle, I was 15% already into Compiler before the changes, and the display was at zero). After my turn in a few ago, I completely skipped over a rank (Cataloger) and went to Collector, lol. This has been the best way for me to make credits with the short amount of time I play.
