I think there is some bugs with the eventing I never got to fix. I think you can get around it with standing before him when speaking... I don't think I have all the files for the game on my computer anymore, so I don't think I can fix the issue.
It is good that it works now. It was weird for the beta testers when I made it too, but most of the times the events wouldn't hang up. It all dependend on small details as to where you stood and similar.
