Hello, every time I try to sit down with haskill for the first time, my Guy just sits there looking at the chair and does nothing. I can't move or do anything. I've reloaded my save and tried all angles. If nobody knows what to do, does anyone know the console command to put me right after that area in the quest?

Have you completed Knights of the Nine?

On the Character its glitching out with, yes.

It's a known bug:
