So I'm running a brand new character through the main/alliance/mage questlines, starting in AD. The last quest on Kenarthi's Roost is to go repel the Maomer, which you go into the tunnels, get the lodestone, and disable 5 wards enroute to the end. Beginning this, they gave you an NPC - (I took the melee which I have done countless times in the past). I have never had any issues.
THIS time - the NPC has been 'adjusted' to constantly stand almost on top of your character, no matter where you move. The interaction to talk with the NPC supercedes all other interaction - like say - USING the lodestone to deactivate the wards.
Why was this change made? No one Asked to make deactivating the wards much more difficult.
