Two days ago, two of the old PVP graphic issues have come back:
1. Birds-eye view issue: After advancing through a defense, there are soldiers shooting from the ceiling while the main opponent is still in the normal horizontal position of the game.
2. Running out of scenery issue: After advancing forward one spot in the defense and trying to move to the right position, your avatar runs out of the game scenery into what has been previously called "the black void" while being shot from behind.
iPhone 4, usually.
