Greetings from Canada friends. This forum helped me out a lot in the early days so I'm hoping it might be my turn to help you.
So that bug we all know, (mostly in BNW) once that happens both teams just stare at each other like morons. Nothing to do but exit and take the loss right?
Try swiping the screen as if you were switching to past or future attack. Saves me 8 out of 10 times. Hope that can help you.
Cheers guys.
