I'm currently stuck on chapter 6 of the game. I'm playing on Playstation 4, and every time I enter the arena where you have to shoot at the zombies operating turrets that shoot arrows at you one of the turret boxes is completely invisible. The zombie will appear floating in the air when he's supposed to be shooting, but I can't hit him to cause the next scene to start. I've tried everything to circumvent this... Every time I wipe my save data or game data and get to the same spot the exact same thing happens. Reloading the chapter doesn't help. Reloading my save file doesn't help. I just want to be able to keep playing the game!
