Found in a Fire plane random, the quest in the area EQA - Fire - Myrmecoleon Tomb has a few issues:
1. upon defeating the boss, there is no completion trigger, not allowing for a turn in at the end.
2. 90% of the chests were empty, and the few that were not, dropped pick up trash (Items that drop upon defeating a default enemy).
Should be fixed; let me know if not.
