When the druids and Taverley as a whole were first graphically updated, the Druid robes themselves did not receive a graphical update, nor were they updated when the Troll Warzone update was released.
With the release of the Troll Warzone update on 31 January, 2012, Druid's robes were unintentionally discontinued, as the druids and druidesses in Taverley were made unattackable. Jagex eventually fixed this oversight by making chaos druids drop them instead.
During the early days of RuneScape, druid's robes were once popular among players as they were the only white robes available at the time. However, with the release of the Tourist Trap quest, their popularity dropped among players as the desert robes released with the quest were identical in appearance and are easier to obtain. The desert robes have since been graphically updated and are no longer identical.
