I'm sorry, but an uncaught exception occurred.
While running game code:
File "renpy/common/000statements.rpy", line 531, in execute_call_screen
store._return = renpy.call_screen(name, *args, **kwargs)
File "game/scenes/hotel_ballroom.rpy", line 6, in execute
File "game/scenes/hotel_ballroom.rpy", line 6, in execute
File "game/scenes/hotel_ballroom.rpy", line 10, in execute
File "game/scenes/hotel_ballroom.rpy", line 11, in execute
Exception: Imagebutton does not have a idle image. (auto=u'images/episode11_GS//ballroom_bn1_%s.png').
that's the end for me
