Yes!!! I Finally Got It!

Just try on a day when you've been finding other rares. You know, one of those days where you, for some reason, keep finding rares you're not even looking for? That's the theory I've been working off of for a couple of weeks now and it's proven to be slightly helpful. It may be day-based (as opposed to the "time" theory) - once recently I played VHard Mines on a "lucky day" for my FOnewm, and finished off Vol Opt at about a minute before midnight. Sure enough, he coughed up a Guilty Light. Theory needs tweaking though... and it's not always true (my latest rare, the double saber didn't seem to follow that rule).
