Ah yes catalyst's usual high standard of editing, this is part of why I'm not buying any more books from them. Although I know have the image of a smart toilet with matrix connections and AR for the potty training of young children.
As far as the "high standards" jab, I really can't agree with you. I've seen worse editing by metric crap ton loads from larger gaming companies who have raked in more cash and had more full-time staff than CGL. WotC, in their 3.x/4e days. White Wolf in their OWoD days. Edit to add: WotC isn't really that much better with editing now than they were then. They have fewer, prettier books though.
The commode thing just makes me laugh. Your/you're and their/there and could have/could of don't seem to come up as much as some books I've read through lately and that leaves me much less holding my breath and turning green than I might otherwise be, and I'm at least grateful for that much.
What I will agree with is production of errata to fix those errors that come up is rather lacking
