Good day, sir.
I'm creating visual novel by naninovel, and following guide in official document.
Everything is ok but loading.... The save-loading system does not work. Game loading never ends.

Can be it problem if I use korean script? My script is written in Korean and Old Chinese alphabet character (in taiwan).
Please give me guide if some knows.
My Unity version is 2019.4.35f1 and Naninovel v.1.18

Sorry, I have solved this problem. The problem was the wrong script, like '[가나다]' text in my script. Sorry for wrong question. This post may be deleted I think.
