Didnt read the 7 pages, so sorry if this is known
I got a loop of the Draw Screens in the middle of a atk animation. Luckly, was my last hit, so I hit Continue several times to advance the frames and get the kill. Maybe I would be locked if no one was attacking.
Sometimes, in the result screen, I got no buttons and have to hard reset the app. The screen shows no points, only 0's.
Sorry, no pics of any.
