So I ran through this quest, went all the way down the reverse tower to find Solta Sil, beat his shadow- so far so good. Upon defeating Soltha Sil's shadow he says some crap about his room is no place for mortals and opens a portal back to the brass fortress and says to speak with him there. Fine. I enter the portal he makes and get teleported, and now here's my problem...

When I took the portal, it dropped me off in the Basicilica at the Brass Fortress. I went outside (as guided by my quest marker). Soltha Sil is SUPPOSED to be just west of the entrance to the Basicilica, but he ISN'T THERE. I get right on top of the quest marker and it says he is below me. There is no way to go down from that spot... There are no buildings I can enter that don't redirect me back out the door I came in from. Everything on my compass and map says he is standing right outside the door to the Basicilica, but he isn't there. I tried relog, restart, even re-install- always the same result. Has anyone else had this problem? Where the hell is Solta Sil really standing? I would like to put this quest behind me so I can progress the story here but I'm completely blocked!
