Patch 26.4 Known Issues (Updated: June 6, 2023)

Update: Known issues list has been updated with a few more points.

Blizzard posted a list of known issues for Patch 26.4. It’s a major update, those usually fix a lot of problems, but also come with their own list of bugs.

So far the problems include Duels runs not retiring properly after the season reset, problems with Abyssal Bassist‘s card text in some languages (it’s tiny and hard to read), and blurry screen between games persisting on mobile.

Check out a full list below. We’ll update it when some new issues pop up or we get a hotfix:

Patch 26.4 is now live, bringing with it the end of all music or your opportunity to save the sound! Find out with the new 38-card Audiopocalypse Mini-Set. Follow this page for updates on list issues we’re tracking with this patch.

The issues we’re tracking this patch include:

  • We’re investigating an issue where decks that do not have a card back assigned are treated as being assigned the Classic card back. You can assign a card back to a particular deck or uncheck “limit to favorites” as workarounds.
  • We’re aware that ongoing Duels runs did not retire with the patch. Instead, the season reset will happen when players finish the run on their own (either by retiring or playing all their games). Players who had an active that would have been retired with the Patch 26.4 reset will be granted one Tavern Ticket in an update soon.
  • In Duels, Uber Diablo’s effect is shown as a “Battlecry” effect, but it actually triggers upon transformation. This is a text-only issue: the effect is intended to go off upon that transformation, like it does.
  • [Resolved 5/31] The team is aware that old Adventures are not being offered for Gold as intended, and is investigating the issue.
  • [Added 5/31] We’re aware of a text issue with Abyssal Bassist in some languages. This is expected to be resolved in an upcoming hotfix patch.
  • [Added 5/31] On mobile, the background screen-blur between games does not go away. The team is expecting this to be fixed in the next major patch. In the meantime, all the buttons still function for switching decks or navigating away from the screen, and navigating away from the screen should reset it and remove the blur.
  • [Added 5/31] The team is aware that the regular Audiopocalypse mini-set can’t be purchased on the web shop (only in-game). This is expected to be added to the web shop in an upcoming update.
  • [Resolved 6/1] The team is aware that Arena leaderboards are not representing correctly, and is working on the solution.
  • [Added 6/1] The Lilith card back is currently showing as able to be purchased in the collection, but it can’t actually be purchased. Players who try to purchase it instead get the Secret Level card back (the card back previously granted by the Dark Wanderer Tavern Brawl).
  • [Updated 6/2] The team is aware that the “New Cards” tab is causing some issues viewing the collection on some devices. The button has been temporarily disabled due to these issues.
  • [Added 6/1] The team is aware of a visual bug where overdrawing at 10 cards shows the card burning animation coming from the wrong deck. This is a visual-only bug.
  • [Resolved 6/2] The team is aware that Magatha, Bane of Music is unintentionally revealing all the cards drawn.
  • [Added 6/5] The team is aware that a stolen Snapshot (the card generated by Photographer Fizzle) will not grant any of the snapshotted cards.
  • [Added 6/5] The team is investigating reported issues with Discover effects and triple-rune cards, Vulpera Scoundrel, and Hipster.

We will continue to update this post as we get more information.

    I find it funny that (at least in German), some cards are wrongly translated and nobody seems to care about it.

    Felerin, the Forgotten – Battlecry: Add a random Outcast card to the left and right sides of your hand. They cost (2) less.

    The German version translates to – Battlecry: Add a random Outcast MINION to the left and right sides of your hand. They cost (2) less.

    Reverberations – Summon a copy of a minion. Each one dies after taking damage.

    German version translates to – Summon a copy of a minion. Minions die after taking damage.

    When you look at how significant the difference in information is, I wonder why those mistakes aren’t fixed. Well, seems like Germany is a market too small to bother. 😉
