Is it intentional to have to/be able to fight Ivo over and over again in the Sanctuary dungeon's 13th floor? I've fought and defeated his three Bone Dragons at least 3 times. Once he wiped out my party.

Every time I leave and re-enter (using a manual walk-out, a game shut-down and auto-return to town due to inactivity, and a deliberate "return to town portal" departure) the "presence" returns and I have to do the fight again. I don't have enough creatures to make the recipe, so I'm not sure if I'm ever getting to keep the recipe I win at the end of every fight or not.

Is anyone else having this bug?
