Some players have had difficulty finding Acantha since she seems to fade in and out of appearing on the map. (This bug may because she is on the static NPC timer instead of registering as a contact.) If players cannot find her at her location, it's been suggested they retreat outside drawing distance and then return (repeat if necessary).
Credit to players Tymers_Realm and Zombie Man for breaking the news about this NPC on the official forums. — Preceding unsigned comment added by Eternalgentleman (talk • contribs) 22:18, 2 October 2010
