In the build editor, typing in a text box disables keyboard inputs even after clicking off of the text box, pressing "enter," or saving the build. This makes the menu stuck open despite any B key or ESC inputs. Only clicking the close menu button will allow the menu to be closed. Other build...
I'm having this issue and another one that's the same except the scrollbar doesn't jitter and you simply cannot scroll to the bottom of your friends list. Still in the game as of current build, 8:10 est july 31.
