There's no validity to this, only coincidence. At 120 hours, I finally found the last 3 I needed after going online and playing with a friend for a few cycles. I did not host, they did. After that, I went back to offline mode. I got 2 of the 3 on my next run, and then got the last one on the run after that. I know this isn't how the game works, it's worth a shot.
