Skeleton of lady arish is bugged

Hi, i just encountered lady arish and she's bugged. The sprite is invisible, health bar and level too. AND my char and the companion turn invisible when near her, even the corpse (yep, i managed to kill her, just slashed enough time). Left no loot but that's normal.

That's probably the bug with the SE corner at Idaya Tomb. I'm working on it.
