I just finished reading a Star Wars Legends book, which was book 1 of the Corellian Trilogy, called “Ambush at Correlia” by Roger McBride Allen. And there was atleast 24 various typos throughout the book. From missing letters, to the wrong word, the wrong tense, wrong capitalizations, and mixed up letters.
The book is a First Edition soft cover, and I’ll leave some examples in the comments.
I run Paizo APs, so I nominate all of them. I know it’s from them writing chapters simultaneously so they can keep to a mo they release schedule, but some are really jarring. Currently running Triumph of the Tusk where one chapter starts with a character giving a speech to the party, despite having been killed off and replaced in the adventure background at the start of the previous chapter.
