Guild Wars 2

The sword drill sergeant (one of the activity to gain the heart) doesnt block any attacks like in the past and just let u autoattack her till u complete the heart.

Knowing what server/world you are experiencing the bugged NPC on would be helpful to the devs so they can track down the problem and fix it.

I was recently by that area on a new alt in Piken Square, and it was definitely doing it there. Sword didn’t block anyone, and the Shield didn’t attack anyone to let you try and block. The Rifle one worked normally, though.

Same on Whiteside Ridge.

• NPC – Sword Drill Sergeant & Shield Drill Sergeant [ 1 , 2 ]
  At the Township of Claypool in Queensdale the Sword Drill Sergeant has her sword sheathed and the Shield Drill Sergeant does not have a shield so players cannot train with them

It appears to be game-wide and not world specific then.

It is possible that this issue came about when they fixed the bug that caused players to see everyone else with their weapons drawn at all times. It seems likely that the related issue of miniatures with weapons always having their weapons sheathed came about at the same time as the ‘player weapons always unsheathed’ issue was fixed. This issue will likely also be fixed soon as a dev stated they were looking into the miniature’s weapons sheathed issue. Fixing one will likely fix both if they are, indeed, related.

• Mini – Weapons Sheathed [ Dev Response ]
  Minis that possess weapons incorrectly have them sheathed at all times
