When studying with Zein on the second day, if the player reads all the books he will enter into a dialogue that will continue looping preventing further progression of the game. Also, there are times when Kyuga will refer the protagonist as Korrin even if the player has changed the name.

That first bug has been fixed on the Patreon version, but may I see the screenshots of where the name is incorrect, I have fixed them but I may have missed out. Also do join my discord as I do share any bug fixes I've done there, and reporting new ones for me to fix will be easier
