Broken NPC: Bibimu

[GalfusBrimstone]

Time: 2:30 AM
Frequency: 100%
World name: Sargatanas
Character name: Galfus Brimstone
NPC name: Bibimu
Monster name: -
Class/Level: BLM Lvl.34
Party or solo: N/A
In-game time: 2:33 AM
Area and coordinates: The Sunken Temple of Qarn - x-25/y-12
Steps:
1. Attempt to speak with Bibimu after acquiring either quests: "Braving New Depths" and/or "Rock-Solid Defense"

Result:
Bibimu does not respond to user interaction. This breaks 2 quests and is a progress stopper: "Braving New Depths" and "Rock Solid Defense". Connection specs and system specs are irrelevant, as I am sitting by the NPC confirming with every other user (over 15 so far) that the NPC is unresponsive, which implies a server issue. When right-clicking the NPC, the hot bar darkens briefly.
