Frequency: ~2-5% of the time I switch mobs
World name: Odin
Character name: Bar Boron
Steps:
1. Engage with several monsters
2. Remove target Lock-On
3. Use directional pad to tab target to any near by enemies
4. Press 'A' twice to confirm and engage with auto attacks


Doing this can sometimes cause my character to lock on to the enemy I have just engaged. I have turned off the auto lock on feature so it should not do this when engaging any enemy however it will only do it mid battle.
