Using the comments here, I have compiled an errata page for the Fantasy AGE Companion at my (unofficial) Errata Archive. That errata page will omits any changes that were made in the first printing in response to feedback here, as I believe the PDF should be updated to match. (There is also new commentary there by me that I haven't posted here, because I still had a couple chapters to finish when I received my print copy.)
I'll check and add gabeprime's most recent comments (5/17 and 5/18) when I have time. And if you find more issues with the book, please keep posting them here, and I will do my best to add them to my archive in a timely manner.
