Update >> Having downloaded the "30 May" killer linked here, I see it is a repeat of 29 May. Although the puzzle’s date has changed, the puzzle itself has not. The site may update during the day, so if you are going to download today’s puzzle and have already downloaded the 29 May edition, check first. I assume this is a bank holiday glitch, and will provide a status report tomorrow.
