It seems those errors
are still in the text. Well, the errors in chapter 29 and 30 are there. I must be dull today, as I can't spot the third error in the book or in what you've typed.
There is a place to report errors in final released ebooks (Not in eARCs or snippets or part-months, as those are all non-final text anyway.)
Send an email to
info@baen.com, give details like you've done above, and hopefully they'll get fixed (eventually.)
And yes, that "1" instead of "I" might well be an OCR error. Echoes of Honor was originally published before webscriptions started, and they might have had to work from a printed book.
