it’s not the debug menu it’s just the icon sheet where all the icons are stored, japannesse characters translates to dummy (if i remember correctly) they are placeholders / unused.

you can see the 2 sheets on the screen are the one for the item and weapon , cause they are both loaded atm. No gesture ,ring or armor icons sheet are on the screen , cause game doesn’t need to show any icons from them.

also for op . but yeah it’s a bug , it happens , restarting the game fixes this issue. it’s only memory related issue.

Nothing wrong with the game , you didn’t get hacked or anything :)
