(Update: Hotfix For Mobile) Hearthstone Patch 27.4 Known Issues

Update: Known issues post has been updated with some new problems. We also have a mobile-only hotfix for players who had troubles logging in.

Patch 27.4 has dropped yesterday, and just like every major update, it launched with a bunch of bugs. Some are smaller and you might not even notice them, others are… more important.

For example, if you see your antivirus app flagging one of the Hearthstone files as malware – don’t worry, it’s a false positive and should be resolved soon (there’s no actual malware in there).

No matter if you have been enjoying the new Anomalies or not, you should probably skip all of the “Start of Game” cards for now, until they are fixed. Anomalies seem to have weird interactions with cards like Prince Renathal – they might not trigger their effects at all.

We also have a bunch of other issues for all major game modes, often related to how Anomalies interact with different cards.

You can find a full list of known issues below. We’ll keep it updated and post about any hotfixes that get released.

Patch 27.4 is now live and Yogg-Saron is unleashed from his prison in the new 38-card Fall of Ulduar Mini-Set! Follow this page for updates on issues we’re tracking with this patch.

The following are some of the known issues we’re tracking this patch:

• [Added 9/19] We’ve received reports of antivirus software flagging “audioplugin_fluxer.dll” as malware. This is a false positive that has been submitted to the antivirus vendors for clearance. The file can be safely restored without risk and we are working to clear the flags as quickly as possible.
• [Added 9/19] The team is investigating an issue with Battlegrounds games unexpectedly hanging. Maiev has (ironically) gone dormant and is temporarily unavailable as a Hero until a fix is found.
• [Resolved 9/22] Some Hearthstone anomalies have unintuitive interactions with Start of Game cards such as Prince Renathal. A fix is coming in a future hotfix patch.
• [Added 9/19] Player records may not be visible in Duels games. The team is investigating the issue.
• [Added 9/19] Some Duels Hero Powers are visually incorrect in hero selection. The hero powers should work correctly in game and the team is investigating the issue.
• [Resolved 9/22] We’re aware that some games vs official bot opponents may not have Hearthstone anomalies. A fix is coming in a future hotfix patch.
• [Added 9/19] The description of the Clockwork strike incorrectly notes that the strike can be earned by completing the Battlegrounds season 4 pass. This strike is only available as a direct purchase and can be obtained now. The description will be updated in a future patch.
• [Resolved 9/19] Players were able to select the same option multiple times from Bound Souls created from Souleater’s Scythe.
• [Added 9/19] Sargeras was adjusted to no longer interact with the original Twisting Nether token if he is copied from the enemy board. For example, if you Reverberations an enemy Sargeras and choose “To The Void!”, no minions will be sent to the Twisting Nether. This is an intentional change and the patch notes will be adjusted to incorporate this note. We apologize for the missed communication.
• [Added 9/19] The team is investigating issues with the Duels collection appearing empty during deckbuilding on mobile clients only. As a workaround, after selecting your hero, restarting the client will allow you to build a deck. Desktop clients are unaffected at this time.
• [Resolved 9/22] Finale cards “glow” at incorrect times when costs are adjusted by outside factors such as anomalies. A fix is coming in a future hotfix patch.
• [Resolved 9/22] Hardcore Cultist and Concert Promo-Drake cannot trigger their Finale effects when costs are adjusted by outside factors such as anomalies. A fix is coming in a future hotfix patch.
• [Resolved 9/22] Some weapons that adjust their own stats, such as Spirit Claws, were not fixed in the most recent bug fix. A further bug fix is planned for an upcoming hotfix.
• [Added 9/20] The team is aware that some Battlegrounds players can’t see the game’s Anomaly during the hero select screen. This appears to affect iOS devices. We’re investigating the cause and working on a solution.
• [Resolved 9/28] The team is investigating reports that the “Experience an Anomaly” Event Quest is not working.
• [Added 9/26] The new Match Fixing Battlegrounds Anomaly has been removed from the Anomaly pool due to a bug causing disconnects. The team is investigating the issue and may return the Anomaly to the pool once the issue is resolved.
• [Updated 9/29] The team is investigating reports from players on mobile devices that they are being prompted to get an app update from their app storefronts when there is no app update. As a work-around, several players have reported that the issue resolved itself by simply force-quitting the app and re-opening, and repeating that process until the prompt stops appearing. Update: we have released another hotfix update for mobile that should address this issue. That update has gone out and will be available on your mobile device as soon as it is cleared by that the applicable mobile device storefront.
• [Added 9/29] The “Alone in the Dark” Event Quest is supposed to progress whenever you play or destroy a Titan. Instead, it is progressing whenever you play a Titan or a friendly Titan is destroyed.

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