Although there is a tiny chance the bug in question may appear in the demo, it is very, very unlikely.
However, it is very likely in the final version if you have advanced to the later stages of the game.
That said, if you have the latest demo, you can keep it until the next real update.
If you play the release version, please uninstall the game and reinstall it.
I'm really sorry for this.
-A new feature of the previous update has been hot-fixed. Sorry for the inconvenience.
-1 item description typo fixed.
