I'm annoyed they didn't fix that idiotic Penitent Engine misprint. I mean, I assume everyone reads it as 1 with the option of up to 2 more, but that's not what it says and we all know there's someone out there who'll argue the toss about it for three hours.
Perhaps this means squadrons no longer exist in 6E? Has any of the newest codicies had squadrons of any kind? I can't think of anything really since IG with hellhounds etc.
