Using either Aerial Assault or Dive Bomb causes the falcon to stop attacking enemies with default attacks/thrown feathers and flies around the character passively. The falcon appears to be responsive to attack commands, and moves to the location targeted, but still does not engage any enemies. This happens regardless of minion stance, and appears to last indefinitely. The falcon returns to normal after Falcon Strikes is used, but the bug immediately returns once the other abilities are used again. The problem persists through game restart and resummoning the falcon.
This has a major impact on my build because it is playing without its major class feature in between Falcon Strikes cooldowns.
