There's something odd going on with this quest line.
After handing in the weapons and shield for stage 13 of Assisting The Watch, Centurion Greogor sent me to talk to Quaestorion Melinda. The first thing I noticed is that the quest marker took me into the barracks, but not to her. Once on the roof the quest marker was positioned on an exit from the roof. When on the first floor of the barracks there was no quest marker showing at all.
Quaestorion Melinda had no question mark above her or anything and she would only speak to me in NPC chatter. From the text in the quest book I assume I'm suppose to battle up on the roof there. Thing is, I already did battle up on the roof at the end of Rites Of Passage which I completed before finishing Assisting The Watch.
Once I gave up on trying to get some quest interaction from Melinda I went back to see Centurion Greogor. He talked to me in quest mode as if whatever I was supposed to do with Melinda happened as it was supposed to happen and let me advance to stage 7 of Tasked With Rebuilding.
