Hey I'll try to take a look at this. There have been 
a large number of changes to how dialogs are done 
since I wrote it.

At the time there were a number of things included in 
the updated tania quest set that we had not 
implemented before (previously the quest was 
inaccessable and completely broken), one of them 
being a multi npc dialog.  Y'all probably have 
figured out a simpler way to do this.
