Act 3 quest - Avenge the drowned prestess - bug?

[lundoki]

Hello!
So i did the quest to avenge the drowned Umberlee priestess, i went to the submarine and found the dwarf, and i killed him. The quest says i have to go back to Allandra Grey to tell her, but when i talk to her, i don't have a dialogue option to say i killed the beast's master. I only have "not yet", or asking to be reminded where i can find the beast... Did i d something wrong? Is the quest bugged?

Probably a bug, report it to Larian https://larian.com/support/faqs/how-to-submit-a-bug-report_85

The way this quest is supposed to go is that you have to talk to him first, and then he takes you to a place... you do something there, comes back, and priestess will be waiting for you in that area and you'll make a decision about the dwarf. But yeah, maybe a bug happens when you kill him straight up.

I actually didn't want to go to this area, i know what goes on there from a previous playthrough, and i wanted to side with Gortash. I guess i'll try to report it, thank you!
