I've noticed that at least two of the comics I've tried to download have ended far before their current page. XCKD ended after downloading 559 strips (odly enough it says its on page 562), and in my previous testing sluggy freelance ended early too, but I do not recall exactly when. Any help in rectifiying this issue would be appreciated. Also, do you use github or any other program for issue tracking?
EDIT: Moving xkcd.def to a new install caused it to update, and start downlading more pages of XKCD. I will update with what it stops too.
PS: I don't want to be annoying with all of my bug reports. I'm really enthusiastic about this prgoram and I want to see it working to its full potential. I hope that helping report issues will help make it better. As soon as I figure out how to make my own definitions I want to do that, to give back to the comminity.
