Warning: wall of text ahead.
Ok, so I definitely broke it lol. Once I realized what engine the game was made in I started using the "Z" and "X" keys to open and close menus. The game does not like this.
Apparently using the default "X" key will go back to whatever menu/menu option you were at before. This seems to cause some issues. I tried to back out of building banana farms (I can't remember if I hit "ESC" or "X" to be honest) and instead all the GUI's disappeared and I was moving the background image of Casa Grande as if it were a character sprite. Hitting "ESC" brought up the party menu, which as far as I know is never supposed to happen. I found no way to make the GUI's come back from this point. Unfortunately I have no way of knowing if this issue came from the update or if it was there from the start. :(
Also, as a secondary, the banana farm dialog points to the country name instead of the currency E.G. it says it will cost me 600 Tropicos (country name), not 600 Gorditos (my currency name).
I have to admit, I love when people use programs to make things the program wasn't meant for (I do it all the time with AGS). Really clever stuff using RPGMV like this :3 I know what a pain it is but I'd honestly recommend you check out Adventure Game Studio, it was made for stuff like this.
I'll keep poking the game and see what else I can dig up.
