But you don’t need to worry even if you did get an older version.
If you played The Witcher 3 on Xbox One, and also decided to download the game’s expansion for that console, you may have a bit of an issue- CD Projekt RED mistakenly released an older, outdated version of the expansion to the Xbox Live Marketplace for a while. The problem was identified and corrected quickly, but in that period, you may have downloaded the older version by mistake.
“It has come to our attention that an incorrect version of Hearts of Stone was accidentally released to users that purchased the expansion pack before yesterday,” CD Projekt RED said. “Since that point the correct version has been released. If you’re concerned that your version of the game is not up to date, don’t worry — any affected copies of the expansion pack will be automatically updated to the newest build without any action required on your part.
“We would like to apologize to all the gamers affected by this problem.”
So, there you go- even if you did get the older version, don’t freak out, it’ll be updated to the proper build by itself.
