Cooking to be sure, but adobe doesn't like/can't find whatever font 'fanzine' is, so the titles of several important parts of the rulebook can't be read.
I have an analogous issue; I'm on Atril and the headers just render as a plain font. It looks like the issue is the fonts are not embedded in the document.
Edit: Tom has said on the Pilot NET discord that an embedded-font version is incoming, which should fix this.
