Date & Time: 6/3/12 - present, during hamlet defense or guildleves
Frequency: every hamlet or guildleve that I'm involved in or near
Character Name: Adiyah Tulika
Race: Seeker of the Sun
World: Durandal
Class/Level: BTN/MIN, 50/47
Area and Coordinates: Iron Lake, all three Hamlets during battle phase
Party or Solo: Solo and 8-person
NPC Name: none
Monster Name: Hamlet beastmen, and guildleve mobs (drifting anemone, bomb-like leve mobs)
In-Game Time: hamlet battle phases for all three locations, ~5p PST for most recent occurance at Iron Lake
Steps:
1. out of range of mob
2. mob dies
3. come within range after death
4. incorrect icon display

This isn't a random occurance, I can force it to happen by simply running completely out of range until the leve/hamlet mob dies and then running back.
