Concerning Bosses...

Certain bosses such as the Spallers, Tree Bosses, Chaos Dracus, etc. refuse to sit still when engaged. It's movements have no clear pattern and are quite unexpected. Sometimes the boss goes back to its original spot while aggro'd and heals all its HP. At other times (mainly when the party is dead) the boss will disappear and continuously fly/run off in a random direction for meters and meters (The longest distance I've seen is about 5000m). This is an annoying bug that I feel needs fixing as soon as possible to make boss fights cleaner and less hectic.
