when in the final stretch of the missions when you deliver the materials and have the mission to condense the water in the library with slevin
I did not see anything to me, I went through the whole library, I got to the bestibulo in the last room, when I go to talk to Slevin I don't get anything to give him the mission or anything to condense the holy water

I have tried everything, remove the ring, I also tried to talk to him, I also did not get the mission, I have to do something before unloading a secondary mission until I get to him or something they don't tell me I have to do anything else, just go to him to condense the water
