12/6 Update: We are in the process of rolling out a client hotfix (meaning a new download for your device) that includes the following updates:

• Updates the win/loss Arena and Duels U.I. so that players can again see their records during the Battle for Alterac Valley Honor event.
• Removes the “Temp” image echo in claiming Alterac Valley packs; also adjusts particles behind the packs on the ranked rewards screen.
• Adds a temporary solution to a bug that sometimes caused crashes when Zephrys was played. The temporary solution involves turning off some of Zephrys’s animations. We will continue to explore more permanent solutions and turn the animations back on once it is safe.

This hotfix is rolling out similar to a patch release cadence (we just released on PC, mobile is planned for approximately 1 p.m. Pacific).

For Google Play users who are having trouble seeing the hotfix, we have a suggested workaround: go to Google Play → open your profile icon in the top right → open “Manage apps & device” → select “Updates available” → select “Update All.”

Separately, we are also working on a server hotfix (no new download), with the target of releasing it later today; more details to come once it is ready.
