I did and I think the key is really not to kill anyone. Well maybe not the innocent girls, but to be on the save side I didn't kill anyone.
But what was strange is that this time with the queen I didn't get to the treasure. Don't know why. I used the save file from right before getting the queen (or not), and then just replayed the last bit. I don't think I did anything differently with her than I did with Titus, but maybe I missed something. Don't know, but checking the statue didn't do anything.
However, in my first playthrough I did get to the treasure with the queen too.
