Black screen in quest

zalex

Just noticed a bug, idk if its known or not. I was in a quest and taping to move forward on my path but i had no energy. I tapped on the green dot and the energy refill window popped up. Closed it , tapped the green dot again with not enough energy to move forward and my phone screen got a black shade (idk how to explain it, photo below) and the game completely froze and had to restart it. Tried to recreate it and the bug still worked
