Natsai Onai's Owl Post while talking to merchant breaks game.

Its Natsai Onai's first Owl Post you receive, after the audio it'll bring up a prompt that forces you to go check the map. Unfortunately I wasn't aware of this and was checking the wares of the owner of Gladrags Wizard Wear.

I was able to open the map, go through the forced tutorial messages, but when I closed the map it left the last prompt on my screen. I was unable to close the force prompt, and I was unable to access the merchant store screen behind the pop-up. The game didn't crash though so after a minute of trying to get past it, I gave up and force quit the game.
