Figured out that this only happens in Speed up mode. If the games is played at default speed the game works.

Whenever I step out into East Gearen and attempt to battle any of the trainers my screen will black out but I can still hear the battle music in the background... It does not matter if I battle the trainer to the left, right, or in the building to the left. I have 13.0.5 patch installed. Is this a glitch or am I doing something wrong?
