How do you progress with Kate at the library or the game in general.
When you are supposed to choose an answer to the math puzzle, you are unable to use the popdown menu.
The answer button does nothing and the "goto the library reception" button doesn't work either.
Undo last move don't work, but the rest of the buttons and your phone seems to work.
Tried restarting, nothing changed, you still getting stuck no matter the version of the math puzzle you get.
Only change is that now you are unfamiliar with the town no matter what option you choose at the start.
