I can also confirm this bug.
In seems that, because I was all in stealth, that the Hag did not appear : at least that is my theory about the programming bug. It seems like a trigger was bypassed because I was not spotted.
I freed Mayrina, looted everything ... and found the tip on Steam about how you can AOE the bugged Hag. It worked and she never fought back.
