One thing that could drive Arbiters to distraction in their prep, is that pages 327 and 424 have links to an Order section that doesn't appear to exist.
Thank you! That looks like it got left on the cutting room floor in the final push there. I've added the page back in - if you don't feel like redownloading the entire thing, the page is here: https://totalityofygg.com/errata/Orders.pdf
If you see anything else (or if you have any questions) please let me know!
