Strange pet behavior in BC 1

[Holyhunter]

During Bahamut Coil turn 1, just before enteringthe boss's lair, my scholar pet Eos would repeatedly fly away from the battlefield, magically appear next to me, then fly away again. I don't know if others have had this problem but it seems strange to me. Maybe it's because I'm a PS3 player.

this happened to me in CT. My fairy would go down the stairs before KB then teleport back up and start going back down the stairs again. I play on PC so it's not only a ps3 problem. If i moved, she would teleport closer to me, but would still go down the stairs. She stopped once the fight started.
