I don't know when the developer gets around to fixing bugs, so I'll simply post severe and/or annoying bugs here as I play through the game.
So far, I only discovered one minor (potential) bug which is annoying for players that want to achieve a perfect bestiary:
- Bestiary, no. 81: Demon's "Dark Essence" drop isn't registered in the bestiary after having obtained it. At least I got its "Demon Scythe" drop despite a drop rate of supposedly 0% (probably rounded down from 0,x%).
