Flower of Evil
If you click on advanced - characters - Alex and then hit the previous arrow key and go to Tim when you hit return while on Tim's profile you'll hit this error. It doesn't happen the other way though just the one way and it only seems to happen with Tim. Actually it seems Tim might be the problem one. Yeah clicking on Tim and hitting return throws up that error.
I'm sorry, but an uncaught exception occurred.
While running game code:
File "renpy/common/00action_menu.rpy", line 107, in __call__
raise Exception("%r is not a screen or a label." % orig_screen)
Exception: u'Characters_Usedd' is not a screen or a label.
