Maybe it's only my copy, but it appears that the "Rangers" playbook is missing from the list of Crews -- there's a page for it, but a lot of text is missing from it.
I'm looking at the PDF of the main text and the crew sheet, and they both seem intact to me. Maybe try redownloading? If that doesn't fix things, please show me a screencap and I'll see if I can figure out what's going wrong.
