Sadly, I don't have any recorded footage, but this has been happening pretty often for me. Maybe every 3 fleet battles. It happens whenever a ship gets cleansed, either on its own or by the capital ship. The buzz droid debuff be removed from the enemy ship, but the game will still show they have buzz droids. Any attacks will not reduce the stacks, and the will not take damage at the start of their turn. The only way to get rid of it is to reapply buzz droids with discord missile and reduce the stacks with attacks. Is anyone else having this issue?
