A few changes have gone live in a hotfix to improve Hearthstone's collection management and some fun stat issues with Caverns of Time reprint cards. Read on for all the details.

Quote From Blizzard

We’ve just released a client hotfix with the following game updates and bug fixes:

  • [Collection] Fixed an issue where copying a deck code that included a card that existed in two sets, when you had the card in one set but not the other, would sometimes show the card as “missing.”
  • [Collection] Fixed an issue where if a card existed in two sets and you had it in one, but not the other, the card would appear as “missing” when using the “missing” search keyword within the Collection format filters (Standard/Wild/Twist). Now it will not show as “missing” if you have it in either version. It will only show a particular expansion’s version of a card as missing if you filter by that particular expansion.
  • [Collection] Fixed a bug with the Caverns of Time reprint cards where, if you own any copies of the original version and exactly one copy of the Caverns of Time version, the Caverns of Time version would not be visible or able to be crafted in your Collection.
  • [Hearthstone] Partially resolved a bug where Soot Spewer and Spawn of Shadows did not have the stats of their original versions updated to match their Caverns of Time versions (both cards got +1 Health with Caverns). We are also working on a server hotfix, launching soon, which will also partially resolve this bug. Both portions are needed to fully resolve the issue—the client portion updates the cards in your Collection and the server portion updates the cards in-game—so some minor issues are expected until both portions of the fix are live on your device.*

This patch is now available on desktop. For mobile devices, client release timing is based on when the build is available on that particular device’s storefront. Be mindful that if you update in one place (like desktop), you will then be blocked from logging into an un-updated version (like if the update isn’t available on your phone yet).

There are also a couple of new known issues that are being tracked by Blizzard.

  • [Added 9/5] [Hearthstone] If you Renounce Darkness in Twist, it’s possible that you roll Death Knight or Demon Hunter–which aren’t in this Twist season–and your cards cease to exist. The team is investigating. For now, sometimes it’s better to be bad.
  • [Added 9/5] [Hearthstone] There are a couple instances of cards being able to Discover another set’s version of themselves, circumventing the “can’t Discover yourself” rule.
