Is there a menu, and if yes, how do I access it? I'm not really used to RPG Maker MV's controls.

Edit: I also found some bugs relating to the Grocery Store job.

First, you can move when the lady approaches you, and grab the groceries in advance. This is also how I found the second bug:

One of the walking-left sprites of the lady has a crudely-drawn "y" of some sorts in it.

Edit 2: Another bug. You can walk up the waterfall in the Blue Spa.
