Private queues are now open for Vault of Stars. Thank you for your patience while we investigated an issue with certain currencies not dropping from VoS bosses under specific circumstances. We continue to work on a fix for this issue but, in the meantime, groups must loot the items "Ashen Star Dust" and "A Dash of Hope" from the first boss, Royal Gardener, in order for other currency items to drop from their respective subsequent bosses in the dungeon.
We will be temporarily removing private queues for the launch of Vault of Stars on PC. We hope to have these enabled once again soon and appreciate your patience and understanding.
