This post should not be overlooked, as it resolves any of the current issues outside of Minato's home.I've run into the same problem, it seems game initializes some dictionary related to hidden objects in the locations when it starts a new game. So if you have a save from previous version you are missing the new locations. You can fix it by loading a save just before this error occurred, opening the console by using Shift + O combination (to be able to open the console you have to change config.console flag to True in \renpy\common\00console.rpy file) and pasting this line of code:
hidden_places['home_minato_exterior'] = [True for k in range(8)]; hidden_places['konbini_exterior'] = [True for k in range(10)];
It adds missing locations to the dictionary.
At least until it's patched properly.
Thanks for the assist!
