My copy has smeared a bit as well. There is a white part on the magazine, err booklet, that is now completely devoid of ink.
Just a white dot. I have handled it very little. Brought it out flipped through it once. Laid it on a clean table and read a little bit more from it. The magazine is in bad shape already. And I handled it very careful. Bad print product. Not the quality that I have come to expect from Wizards. Not enough art in the book. To many mistakes with the pre gens. To much money for a sub par product.
Having said that. The adventure seems pretty good. And the maps are super cool.
