I've been standing in the field with my merc slaying everything that comes near us and he keeps saying, "Are you sure?!? I can still hear quite a bit of buzzing around here. I am not getting up until the coast is truly clear!"
A word of note, the bixies themselves generally aren't hostile, but will help each other. The drones will attack you on sight though. Also, things respawn pretty quick out there, like maybe 5min respawn.
