For all the errata of all the previous condition and objective cards, as well as command and upgrade cards, are they all printed with the correct errata when the new versions of the cards come out eg. the new core set?

AFAIR: Text corrections are printed in newer versions. Point corrections are *not*

^what he said. The only item with 100% accurate cards at all times should (assuming they didn't misprint lol) be the images on the sides of the current rrg pdf errata section found in the legion d/l page

Hard errata to the core set battlefield cards are printed correctly in the CW core set. Can confirm
