I am having issues battling trainers at the nightmare university as Aetilia where when I am playing in speed up at 2.5x (havent tried other speed but I assume the result might be same) and when I battle someone it goes past the animation of the pokeballs etc showing that it is a battle the black thing comes and goes then it keeps zooming into the screen to 4 pixels. I accidently battled someone without the speed up and that worked well
I have uploaded to screenshots of what end up happening
