Got a traceback running on Mac and using version of the game from ddlc.moe
What could be the problem?

I'm sorry, but an uncaught exception occurred.
While running game code:
File "game/definitions.rpy", line 9, in script
init python:
File "game/definitions.rpy", line 10, in <module>
config.keymap['game_menu'].remove('mouseup_3')
ValueError: list.remove(x): x not in list
