So, I had been getting the guaranteed blue box at the end of the normal dark dimensions terminal, but today it didn't drop. I figure that it's just a glitch, but I was wondering if anyone else had encountered this.
Update: Well, I just tried it again now, approximately 24 hours after the time I first ran it yesterday, and got 2 blue boxes. Very odd. Must have a 24 hour timer. Or a shorter timer? 20 hours perhaps? Either way, it seems to be on a timer separate from the normal daily reset.
