Sometimes when I'm fighting a peblit or a spookit, it becomes unkillable in the middle of the fight. To be clear, I'm not talking about them being invulnerable in their resting state. I mean that I've damaged them, they're attacking and suddenly I can't do them any more damage. The peblits I can at least run away from but there's no escaping the spookit, it always kills me. Is this by design or is this a bug? If by design, I regret buying the game.

Hi, this is a bug. I have no cue about how to fix it. You can try create a new character and then transfer all your stuff.
