Also have Lohse as my avatar character - just got to this quest and experiencing the exact same thing. Get to the room with thousands of candles, Malady says she will summon a flood if we give her the ok, the companions all give their opinion and then nothing. The flag(s) for this quest is broken in the most frustrating way; another oddity with it is that the quest log gives an update for ALL of my party members (Fane, RP, Sebille) for this part, when it seems like it should be Lohse specific (considering its part of her storyline)...so I feel like that has something to do with it.
Please check into this ASAP as I'd really rather not continue my playthrough without resolving this quest. I found Lohse's story to be very compelling and engaging, and I want to see it resolved!
