Look at the dates, please - page 486 is the most recently uploaded comic. There's nothing wrong with the system! The Looney Tunes and 8 - 9 Regeneration page were posted to separate pages on the old site and ended up outside the scope of the conversion script that bunshichi wrote. I needed to upload them manually after the fact in order to get them into the archives on the new site, which put them out of original sequence.
It's all good, in other words, and when a new page of something goes up, it will be showing on the main url.
Thank you. I'd apologise most humbly, but I don't think it's intutively obvious that a page I saw years ago was the last one uploaded.
(I'm just saying that to hide my embarrassment. I should have checked.
