Announced fixes

Nexon’s notice for the October 15, 2026 maintenance lists these Thief fixes⁶:

• Dark Sight needs Disorder at level 3. The skill text wrongly said level 1.
• Steal no longer drops mesos or items, steals, or gives its buff when the attack misses.
• You can no longer open a Store Permit shop while Dark Sight is on. Before, other players could not see the shop.

Nexon has not announced other Thief skill changes for Classic World.
