When the enemy's pokemon kills itself first (using self-destruct or some other method) and my Pokemon didn't move yet and I switch out to another Pokemon, my 2nd Pokemon uses the move that my 1st Pokemon didn't use yet even though it didn't have access to it. For example, I was going to use Dig using Vibrava when the enemy Voltorb used Selfdestruct first, and then I switched out to my Blaziken. My Blaziken doesn't have Dig, but it used it automatically before the battle menu showed up.
This has happened on more than one occasion for me. I didn't see this on the list of known bugs so sorry if this has been brought up already.
