10.0.5 Known Issues List // Updatded January 25

Classes

Druid

Players logging into 10.0.5 as Balance specialization may be unable to use or select some of their Talents in the UI. Logging out and back in will resolve this issue.

Rogue

Some Rogue talents cannot be untalented from the UI without untalenting the entire Class tree. Players can also make a new Loadout to avoid this issue for now.

Events

An error will occur when players leave a Trial of Style before it begins.

Items

Items converted by the Revival Catalyst may unintentionally retain their ability to be converted.

The upgrade preview for War Mode or Storm items may display a higher item level and stats than the player will actually receive.

Transmogrification

Attempting to apply a weapon illusion sometimes doesn’t work.

User Interface

Dragonflight class set bonuses are disabled but will appear active in the tooltip while inside the Mage Tower challenge.

While the Trading Post is not active yet, the Traveler’s Log tab will appear in the Adventure Guide with an incorrect tooltip.
