She posted the reason for this reset on her site:

I’m not sure what to make of this, nor am I sure that I like it (but hey, don’t listen to me, I didn’t like that the syndicate decided to keep running Peanuts after Charles Schultz passed away. because now — as much as people like this strip — there is some cartoonist out there (or several cartoonists) who can’t get their work into print because Peanuts is occupying their real estate.
Imagine, if you will, if Schultz had been denied publication because some older “revered” cartoonist strip was hanging on after that guy had passed away. I respect the right for the syndicate to make money, but I think that Shultz would have objected (or sahould have objected) to this sort of thing.
