The bad news is, crontab is a startlingly unpredictable piece of software. I tried to disable the winner-picking script during the patch, but it ran it anyway.
The good news is, it picked a winner properly. Horay!
The bad news is, it reported the wrong isk value for the winnings. This was caused by a debug variable being set, and has been fixed. The lottery page was also fixed, but I used a calculator and a text editor for that.
The good news is, this isn't a substantial bug so we don't need to go another semi-test round. I anticipate going public this Friday, and probably switching to picking winners on Mondays, which means this will be a 6 day round.
As always, I am obliged to spam a link to the lottery page
