I got logged out and now I can't change the theme back to black. I'm on iPad and I can't click on my profile picture in the top right to change the color. There was a menu that used to pop up when you did that if I remember right and either it's gone or doesn't work anymore. If nothing else I might be able to tap on my name when I post this and dig into my settings from there. (Edit: no.)
I ripped my headphones off, dropped my controller, and turned the console off after Man-Bat. There isn't anything else really like that until the last 5 minutes. I had to take my headphones off there too in order to keep playing. Joker pops up in your face like in vents but that stuff is really not too bad and is easy to predict.
