I also recieved a bug after going to Minato's house for the first time. It crashes after the line about where to search for Chiaki.
While running game code:
File "renpy/common/000statements.rpy", line 569, in execute_call_screen
store._return = renpy.call_screen(name, *args, **kwargs)
File "game/scripts/screens/residential district/minato's home/s_home_minato_exterior.rpy", line 1, in execute
