stone sluice
I tried exiting to the stage theater menu where you can access the Behind the Curtain stuff and event shop. Instead it brought me to this screen. My game isn't frozen because when I tap on things there's feedback sounds. But nothing happens when I tap; I can't end the trade, and I can't leave this screen by tapping the back button. I was only able to exit by disconnecting from the server. I wasn't in the middle of a trade when trying to exit to the menu.
