WoW Forever: layering bug crowds a Thousand Needles cave

Layering appears to be broken inside the Roguefeather Den, a harpy cave in Thousand Needles that several quests send you into. Instead of being spread across separate layers, a large number of players end up in one small cave and compete for the same mobs.

The quests affected are Test of Endurance, Stop the Screeching and Stolen Freewind Supplies. Grenka Bloodscreech and the Screeching Windcaller spawn rarely, so tagging them can take a long time.

The layers seem to be only partly combined. Inside the cave you can see other players attacking, but not what they are attacking, and you can be hit by the area silence of harpies from another layer that you cannot see in your own. There is a second bug as well: if the objective does not update after you loot the claw for Test of Endurance, logging out and back in makes it count.

This is one report, and Blizzard has not commented on this cave so far. It follows other layering trouble since launch, from areas that felt too empty on day 1 to a brief clone of NPCs and mobs. Until it is fixed, it may be easier to leave these quests for later.
