So I started ToB today with my Blackguard, did Saradush and went to Watcher's Keep. After clearing the first floor, Hexxat died in the second statues battle. After that, I rested as usual and when Hexxat was supposed to be revived, she just turned into her cloud form, took Dragomir's Respite and went out of the party. No dialogue, nothing. I have tried resting outside, in the pocket plane, in the first and second floor of Watcher's Keep and this always happens. She resurrects, becomes a cloud, floats away and leaves the party.
