World name: Goblin
Character name: Mistasia Mistique
NPC name: Knerl
Monster name:
Class/Level: 22
Party or solo: Party (1), and Solo
In-game time: Server time 5:14pm, Eorzia time 11:54am
Area and coordinates: Eastern Thanalan . Camp Drybone, X14, Y24
Steps:
1. Accept Dressed to Deceive quest
2. Equip Weathered Shepherd's Tunic and Weathered Shepherd's Slops
3. Talk to 4 NPC's
4. Attempt to talk to 5th NPC (Knerl) to complete this part of the quest, but Knerl does not respond when right clicked. Skills on hotbar briefly dim as if a chat dialogue box will appear over them, but then return to normal and the quest progress stays at 4/5.

I've tried logging out and back in, and it appears as if this bug is affecting many people because there are several others standing around me emoting at Knerl in their Weathered Shepherd's gear also unable to complete the quest...
