If you rescue TR_m4_V_Alvayah in a Baluath quest, then exit the dialogue window instead of recruiting her, she'll be greeting you with "Do not bother me, %PCRace." and a Goodbye. To fix this bug, change the dialogue filtering in one of her greetings 2:

"Death's embrace, my friend. Thank you for rescuing me from that wicked sorceress. I am Alvayah, the enchantress. Perhaps you are familiar with the name?" - Journal >=30, Journal <60
